Just a painting update. Will start other printing tonight (off-peak and all that) of seats, steering wheel, fenders (version 3), and other accoutrements. Then assemble the wheels now that I found my wire spool (lost it under all my other junk). Must admit it does start to look like more real for some reason. Cheers.

Arnhem refight project
Was curious as to why my gaming friend requested 30+ jeeps. He gave a throwaway answer about numbers. I didn’t quite believe him. But yesterday I purchased the Operation Market Garden booklet from the Rapid Fire website. I did a quick count of the jeeps required by the Paras and was surprised to find out that my friend’s estimate was fairly accurate (give or take a couple of extra jeeps). But then I did a proper count of the German forces at the Arnhem landing and was momentarily stunned. Lucky the guys in my gaming group have more than enough to help cover most of the equipment required. But it has given me more incentive to use my 3D printer should there be a need to produce a tank or armoured car or flak gun if need be.
Tonight I’m showing further progress on the Willy Jeep print job. Getting into the swing of things design-wise. Reacquainting myself with Sketch Up takes time, which frustrates me no end because I kind of thought once the basics were mastered, it wouldn’t take long to churn out design after design. Wrong. Anyway, I’m having to revise the fender design again as the pieces are quite fragile and snap off easily whenever removing the raft support. I thought I had it sorted out by repositioning the pieces (as seen on the pic below), but I was wrong. So I’m thinking I may need to make both front and rear fenders as a one-piece. Will jack something up and see how the test run works.
In the meantime, I’ve also resized the tyres/wheel as well as the jerrycan, and then discovered neither are really needed on the rear as the Paras added other more necessary items essential to their mission such as soldiers packs, crates of ammo, supplies, and so on. Most of the wartime photos I’ve seen of the battle show the tyres placed on the front anyway. By being an alternate position this placement probably also served as light protection for the vulnerable radiator from stray bullets.
I’ve also redesigned the seating as a separate component. Still got the MGs (various types) to design, the burgen-style packs and tarp-covered stores to be attached to the bonnet. Then there is the bulky radio set for the back seat. The steering wheel was drawn up as well, although I suspect it’ll probably fail when printed because of how small it actually is. Finally, there is the trailer which actually turned to be the easiest design work yet.
I’m also endeavouring to print out a representation of the Tiger II simply because I want to see if it can be done. At Arnhem/Oosterbeek there were a total of 3 heavy tank companies, a heavy tank headquarter and a separate heavy tank detachment involved over the six days. Those actual numbers make for eight (8) on an Rapid Fire gaming table. I’ve asked to the two main guys organising this; they’re happy to help and have offered three (3). But I still need five (5) although I haven’t asked all of the group yet. I’m hoping they’ll have a few more. So I may not need my planned print out but at least I’ll still produce one just to see if it can be done and done well enough for tabletop gaming.
Tonight I finished sanding down by hand the thirty jeep bodies. The picture below shows one lot of fifteen (15) with their wheels. Next to that lot are the jerrycans, now superfluous to actual needs. Maybe I can use them as a temporary fuel dump somehow.
I figure to try to keep it simple by drilling holes into the outer part of the wheel and run wire through them (see below). Then I will hopefully attach the wheels to the bodies before covering them over with modelling putty to help cement them in place. I remember that I have two Dremels so sanding won’t be as tedious as what I’ve been doing tonight. It will also come in handy for cleaning up and detailing the external face of the wheels properly.
The second lot of fifteen (15), shown below. I want to show the detail on the front grill as well as the curved bonnet. The design of the bodies took considerable time as it was the first design work I did. It wasn’t properly planned out and it shows in that there are gaps in places, such as where the occupant’s feet are placed. Also the rear wheel housing has gaps where the design was piled on to one another and creating a confusion of intersections (at least that’s what my excuse is) which was revealed in the printing. I am reluctant to redesign the body at the moment and am therefore happy to just use modelling putty to plug these gaps which was hidden anyway.
Tidying up the general messiness of the printing has taken time but necessary. Thankfully I have the necessary tools to achieve the task, but being lazy doesn’t help with the motivation. But then I always check out the modelling diaries on WAU forum and somehow, miraculously, I get motivated and enthused.
40K Trench System and Display board
Definitely on hold as I sometimes need feedback to keep going. No feedback, no reason for being motivated. With the Willy Jeep, it’s part of an ongoing gaming group project. And the guys there are pretty helpful with the feedback which does help to keep me motivated. But in saying that, I will finish the terrain board within the next three months (among numerous others that are sitting idling on my overloaded workbench). Cheers.

Jeep bodies rolling off the assembly line (3D printer). Happy with the body work although they will be needing a lot of modelling putty in some places. Worked out to print the fenders separately as it was causing headaches when printed (for me). Just need to redo the tyres (too thin). Then I will start on the attachments (medical stretchers, radios, twin Lewis gun mounts, fwd Bren gun mounts, crates (stores basically) to plonk on the bonnet and back, and so on. Should be an interesting few months.
Once I finish these, I’ll start on the German side. Needing Opel Blitzes, Citroen trucks, Opel Maultier prime movers, Horsch staff cars, Steyr Personnel cars, and the like. Hoping the lads will already have these as I don’t need many (apart from the trucks of course).
Should the Germans be sorted out, then I’ll start printing the buildings I started doing in Sketch Up some time ago – the likes of St Elisabeth Hospital, the Museum, several hotels, and so on. These will be the feature buildings of the refight. The rest can be done in plastic card (well, the others can pull finger and chip in I expect). And then there is the bridge.

Finally completed the test dummy replica. It still needs modifications, both major and minor. But it shouldn’t take long to organise that now that the main body is settled upon. I am hoping to start printing these out over the weekend. Once printed, comes the arduous task of cleaning, sanding, painting and basing. Hoping to do several versions – screen absent, screen up, HMG mounted, maybe even a trailer.
This is a rough printout but it’s passable for tabletop gaming. I’m blind anyway so it’s good enough for me. Cheers.

Hit a wall so I decided to just print what I had mangled through Sketch Up today. I’m glad I did cos now I have something tangible to see rather than rely on an image inside my head and a monitor display. That was my wall: reliance on a concept rather than moving on and making it real.
What’s there is decent enough however which is both pleasing and satisfying. I still have to make some modifications on the bodywork before mass producing. I also need to be extremely careful of my geometry; it’s screwing up the faces because the resulting faces/lines are not locking properly. Dimensions are decent enough in the comparison below with some minor adjustments. I now have to resume and persevere to complete this interesting event.
I’ve added the fold-down screen. But as I was removing the supporting frame, the windscreen snapped off. Therefore I will make it an optional attachment, like the jerrycan and the mounted HMG (to be designed later).
I’ve gone with the chunky form because of the size; it’s just not viable to go fully formed, as the previous plan and demo model show. So, things like the front hood can be shaped using sandpaper and a bit of manual labour.
Main priority is to fix up this first-attempt design. Once I’ve tidied up the underside then it’s thirty-plus for the printer. Cheers.

I hate Sketch Up! It can be really annoying sometimes.
Got a new 3D print job – 30+ Willys Jeep in 1/72 scale. Our historical group is putting on a refight of Arnhem some time in the future (planned for 2018 BrisCon this time). The guy organising the refight has a major logistical problem and I said I would help out. Hence, why I am using Sketch Up to free design a tabletop-standard replica of the vehicle.
Managed to do the wheels and petrol can separately and printed them out to a reasonable (i.e., tabletop) standard. Currently working on the main body; got as far as the dashboard before I started encountering problems with Sketch Up’s fmous measure tool. If not careful you can find some of your geometry won’t close because you’ve selected everything but the intersection point. Happens if you’ve been drawing all day, as I have, so I shouldn’t be too grumpy about the program. I’ve used 12D and that’s monstrously annoying.
I’ve decided to call it quits for today. My checklist is as follows:
- Wheels/tyres (5 per vehicle)
- Gas can (10 litre can)
- Rear portion of the jeep (top part)
- Front portion of the jeep (top side)
- Underside of jeep (axle, springs, and shaft)
- Attachments (tow bar, bumper)
The tyres went well. But the handle on the jerrycans were too fine for the printing, which leaves me thinking I may be struggling to add the trenching tool and axe attachments (driver’s side).
Once all the components of the list are done, I will then combine the jeep portions and then print that, attach the wheels and petrol can. If I have time and not get sidetracked, I will look at these extras:
- fold down screen
- .30 cal MG
As for the 40K trenching system, I’m just cutting blocks to insert and then jigsaw a section of thin MDF/ply to place the 3D printed sections and then start terrain landscaping. Seen some really inspiring stuff on WAU forum Modelling Diaries as well as Painting and Terrain. Not trying to match their excellent standard but I am dead keen to actually finish this and put it up for sale at the wife’s craft market next month. The club has enough 40K trenching terrain, so I was told. Cheers.

Made a tentative start today on building the display/battle board using the 3D printed components.
I am using a single MDF sheet cut 2′ x 2′. It’s part of a collection of similarly sized boards that were part of a modular board tile plan that’s sat idle till now.
Because you can go several ways with this system, I’ve taken the slightly different route rather than having it all flat. Mind you, there’s nothing wrong in laying this system on flat open ground because it might well represent the best means for protection for those defending it. If the ground somehow prevents a dug-out protection system, then having it on top seems quite sensible.
But trench systems imply some digging down. Well, I can’t really dig down on an MDF board so the next best thing is to raise the ground on which the system has thus been excavated. As the pic above shows, I’ve cut out strips of Styrofoam (not the good stuff though) and glued them to the board in roughly the position where the system will eventually go.
Firstly, though, I’ve had to reconfigure the system to fit the MDF board. As the pic above shows, I shortened the front line but lengthened the distance between front and secondary lines. I’ve also included the bastion strongpoint that was the first item printed to represent my outpost in the rock face.
I will next rough cut some very thin MDF using a jigsaw as my base for the 3D walls and flashpoints. I’m looking at screwing them to the cut-out MDF plate.
I next need to add reinforcements in the shape of wooden blocks (also screwed and glued to the board). The foam inserts I’ve already glued can help with the shaping of the sloping ground.
Thus far I’m pleased with the modular style configuration possible. Because of space limitations, I was able to adapt my original design (below) to suit.
Changed the tower design because it would take forever to print out. So I’m going with just a blast door to be placed on the side of a cliff face or hill. Print time for this change is considerably quicker, just 50 minutes as opposed to the projected 6 hours for the tower base alone. Will design one of those familiar covered lookouts chiselled out of the cliff face that you see on those space movies to complement the new doorway.
Insect-class river gunboats
Did a quick Sketch Up of the next project. Going with 1/1200 scale for starters. It is a very crude design, modelled on a rough sketch I’ve obtained online. Seems it’s hard to obtain blueprints of original ship designs without paying for it. And I’m not ready to output money for a scale model that’s around 60mm long. Hopefully, I can find some decent plans soon.
The print took only 6 minutes! Scale is 1/1200. And it’s done by eye. But it’s just the first draft. There will be lots of alterations and modifications no doubt before settling on a finished model. I’ve used the freely-available generic dimensions available online. What’s been printed thus far requires some modifying as the printer doesn’t like overhangs/cantilever decks, or double stacks close to one another (it just blends them together which needs carefully paring away with a craft knife).
20 March 2017
Starting up this post specifically for any 3D printing activities planned or happening. But it’s also be home to any Sketch Up design work attempted.
Once more, I’m up doing another all-nighter because it’s cheaper to do this during off-peak hours. That’s the only really big issue I have with 3D printing: it takes a very long time to output anything.
I like to work on a print table of 100mm x 100mm even though it can extend to 120mm x 120mm.
The quality of the Verbatim ABS filament is inferior to the original ABS filament that arrived with the printer. Verbatim is much cheaper and at the time I thought I was getting value for my money. But maybe next time I will spend a little more for better quality filament after seeing some of the recent outputs – lots of stratified lines through the layering process. It’s still reasonable quality – using a suitable sandpaper to smooth the rough parts helps – but will closely watch the quality as I go through both these reels.
To recap on what I’m looking at doing next month: Insect-class river gunboats. At the moment, finances are tight so I have to be careful with what I purchase. The basic dimensions are easily obtained online so I may start with a rough design first. Should I need further detail, I will then make a move towards purchasing the blueprints.
Hopefully I can somehow create a working design that will output. If the result passes inspection, I can then look at casting resin replicas and sell them online. And maybe do it also for the Fly-class ships. I’m hoping there’s room for niche products. Just have to keep motivated. Sometimes, that’s easier said than done.
