Set of four simple 3D printed TPU bands, for holding motor wires snugly onto a frame.
A TPU band is tough enough to be pulled over the arm, twisted, pulled back over the motor and back around the arm, then twisted again, and jammed around the head of the arm at the base of the motor. It will then tightly hold the motor wires to the frame.
Stretching the TPU band over the motors causes it to lose shape, but will still snug down tightly. It’s best to lightly sand any really sharp edges off the TPU before pulling them on.
If removed from the arm and gently heated to around 100C, the band will return to normal shape.
These are much tougher than rubber or silicone bands.
