Thank you! I needed a model to test my Flex PLA.

I am printing your nice tank. What do you use as axels for this?


For this proof of principle design I used long M6-threaded screws (the hubs/wheels were screwed onto them) and ball bearings. The fuselage is not in any way a good design, only a fast base to test the hubs/wheels/tread... the drive-wheel was fitted directly onto the geared-motor axis.

Great design! Are u using a direct extruder for this type of filament?

Most extruders can handle this type of filament but its best if the tube down to the melt-zone is made of PTFE and that its supported very close below the feeder wheels. Print speed is very dependant on how good the extruder design is.
