Treads to try out my own TPU filament... worked great :-)

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.
Different flexible filament would perhaps work, make sure its not too stretchy since it might not stay on the wheels/hubs. I used my own:

It´s 95 Shore A. It is also conductive and if you make both the hubs and thread in this material you will be able to handle the static e
