This is an alternative wheel for the Move-It! rollers by GiantBrian.
It features a slight curve towards the edges and a bit of thread. The thread is off the ground on hard surfaces but should start gripping on softer ground and when making turns.
It's meant to be printed in hard TPU. I used 58D TPU and added enough perimeters to make the wheel completely solid with a 0.6m nozzle. TPU will make it very impact resistant and improve surface grip. Make sure to dry the TPU before/during printing.
