We’re at 40 hours/80% as of now. The scrapped print was 22-23 hours in.
For the first time, I’m attempting to design wheel assemblies, inclusive of the tyres/tires.
Version 1 yielded enough lessons for me to be confident that version 2 will be test-print worthy.
In the meantime, remedial details & ancillary design is underway.
Thanks for looking in.
After almost 52 hours, the upper hull print is done. I’ll let it drain overnight before starting the post print processing.
Hopefully any defects or issues are of the minor or non-existent varieties.
Thanks for looking in.
Looks like I hoped in vain. For some reason, the print is “creasing”, rendering the resultant print unusable.
I’m trouble shooting atm, with options including splitting the upper hull roughly in half so there’s sufficient room to orient the model to the built plate more aggressively.
That said, there’s an opportunity to further refine the model before hitting “go”, so there’s that.
Thanks for looking in.
Regardless of the fail, I finished cleaning up the upper hull & threw together the parts I’ve printed to date.
The Pit Road/Trumpeter 1:35 kit is there for reference, as is the 20mm x 100mm reference card.
Thanks for looking in.
Wheel & tyre design is ongoing.
Hopefully I can bring the tyres to a satisfactory conclusion in the next session.
Thanks for looking in.
As the upper hull reprints were progressing, the wheel hubs & tyres were designed.
A test of solid tyres showed that their weight would induce print faults, so at the suggestion of a mate, I changed the design to take out weight.
Ten, evenly-spaced braces should be enough to take the weight of the finished model.
The hub print went well, but I’m not happy with the beefiness of the lug bolts. They’ll be corrected on a subsequent print.
Still, good opportunity to test fit onto the model as-is.
Thanks for looking in.
With v2 of the tyres printed, time to fit check on the v1 hubs.
In the event I can’t refine them further, these should still be workable.
Thanks for looking in.
Not happy enough with the v3 wheels.
Here’s where they’re at.
With a quick go from a rattle can.
Clean sheeted v4, today.
Far happier. Just needs some detail.
Thanks for looking in.
After further examination of the physical model, I checked the ride height/ground clearance with references. Should’ve been a scale 450mm/17.7”, turns out it was 506mm/20”. As I’d merged the suspension swing arms with the hull, this took some work to fix, as well as an entirely new suspension skateboard print.
I think I’ve solved this.
I’ve used a superseded upper hull print as a paint mule so I can confirm the colours.
Last cab off the rank is the fittings & fixtures work.
Turns out the JGSDF POL jerry cans are virtually identical to US WW2 cans.
Thanks for looking in.
