You have to print it in only two parts, but there is a lot of moving elements:
rotating turret
two moving guns (one main on turret and second smaller on front tank huller)
opened driver's hatch (in front of the turret)
rotating wheels (each of the six wheel can rotate separately)
you have to break small connector, it is only a support needed in printig; to breake it just rotate wheels in diferent directions
Printing instructions:
For “tank turret”:
use “Supports on build plate only”
For “tank main body” and “tank main body (no tires)”:
use “Variable layer height” to get better quality where the hatch and gun are (maybe it's not necessary, but some details could be invisible and some mechanisms (gun and hatch) may not work)
add supports everywhere and add few support lock in this places:
For “6 tires”:
no supports
you can print it using TPU/TPE to obtain better road grip :)
For track (both files):
if you want print it using one material turn it by 180 degrees like this (in this option don't use supports):
if you want print tread (the highest layers) with TPU/TPE don't turn model, just change filament on the right layer (unfortunately in this option supports are needed
For “track pin”:
use brim or supports
Edit:
1.02.2023: track tolerances repaired
1.02.2023: g.code repaired (supports under the turret)
2.02.2023: track tolerances repaired, better holder for front track, added track pin
