Modular tank conveyor belt

With this modular system you can create your own tank, robotic base, and even a wheelchair for a very small person!

UPDATE!
Now you just need a piece of filament to join the sections of the conveyor belt together!
The powertrain is an N20 motor (high torque is preferable to high RPM - the more torque the better).
You can print the complete body (simpler) or you can print the modular parts and make longer tracks (at least that's the idea - I didn't try it. But the idea is good, don't you think?).

The system is symmetrical on all axes, so you just need to print twice as many parts to have both sides.
In the complete version, each track has 30 sections.

Materials needed for each side:

• 2x N20 motors (high torque) - I used two 18650 batteries for power. It won't work with just one battery due to weight and friction. It's for a tank, not a plane.
• 4x M3 screws

Assembly:
Cut the FILAMENT into pieces approximately 34mm long (bend one end slightly so it holds and doesn't fall off during use). Each section is joined to the next by passing the filament pieces through the hole. Even an American can do it.

For the rest of the body, just look at the photos.
