T-34/76 for assembling, with moving parts
Around 1:33 scale
~18cm x 9cm x 7,5cm (19cm long with barrel)
Test-printed (prototype and some part-tests) on JG Aurora A1 with PLA and PET-G.
Rather big Update 09 VIII 2020 - check on bottom.
Assembly instructions to check before buy (it's in the files too):
You can test-print the tracks for free
WARNING: NOT FOR SMALL KIDS
(small parts and some not as strong to be kid-proof)
Model is based on the oldest T-34/76 I saw (thats why all main wheels are the same) and few more photos and blue-print I found.
It may not fit the real scheme (may have older/newer modules that didn't happen to exist in same time on one tank). I'm not really into historical accuracy (nor with my interest nor with informations I have and could get).
Some parts are not as they should be (beacuse of no supports goal and/or no good photos found)
You may print it smaller but you will need smaller nozzle (66% for 0.3mm, 50% for 0.2 etc.) - but then tracks may not work at all (or it can be even too difficult to assemble them, it was not tested.
Or bigger (125% with 0.5 or 0.25 nozzle etc.)
If printing tracks-with-rods use little lower temperature than normal (to not let merge the tracks together - but it depends on printer and options).
Test it on x4 first.
Important note, before you will buy if you want it to be movable:
Tracks may not work as freely as they should - depends on many factors.
I just added 2 more track versions (wide and narrow) so it should be better than before tho.
The most chance tracks will work very well is with 'narrrow' version and with printing this tracks without rods - but there is more work then.
If you just want a model for gallery or sth print normal tracks (best looking, closest to real ones)
Or even don't print tracks and use rubber bands (model from files printed with TPU) for big wheels and play it like a car.
WIP photos and renders (I know that it should be more of it ;))
FREE: Baby T-34-76
Edit 20 V 2020
Updated instruction (added a list of all parts needed, on the last page)
Added a link to free test-print of tracks (link above Instagram links)
Update 05 VII 2020
Small fix of hull_base file (inside faces, intersections)
And fix for tracks-with-rods (4 and 18)
Update 09 VIII 2020
-hull_base - fixes, little changes
-main-gun_barrel_v2 - second version of gun barrel, not as often used but better looking
-new tracks (wide [29-30x2 for one side] and narrow[35x2 on side]) - 'narrow' should work best, normal tracks should look best, 'wide' is sth between them
-track-rod-band - changed a little for less work with tracks assembling - cut in the middle of lines
-wheel connectors - should be less wobbling
-wheel_rubber - to play with a tank on hard floor without tracks - use on at least 4 big wheels
-wheel_small-back - resized to be closer to original (now its bigger than 'small wheel front'
-wheel_spacer-gear_4 - use it for normal and 'wide' tracks to be working better ; normal gear (5) may be better for 'narrow' version but I'm not sure
-wooden-box - new addon (hanging on side handles)
You can print it with PLA but I reccomend to use PET-G for some parts. Like:
and least important but PET-G may be helpfull:
0.1mm layer height recomended (but everything should be working even with 0.2mm; adaptive height may be good too)
No supports (but ofc you can use them if you want)
There is some bridges, I was using 'Bridge settings' on Cura
'fill gaps betwen walls' recomended on small objects
I used 25% quarter qubic infill
'gun_barrel' printed with spiralize option
