I can’t wait to see these in action. That needle cutter mount looks pretty awesome. The wheels should work, depending on the TPU you might be able to make them out of just the one material. You can do a little design cheat.If you want to do a relatively low infill density but are worried about bearing rigidity, you can place a series of small holes all the way around the bearing. if you do this it will trigger perimeter walls around the holes and make it much more rigid, almost like 100% infill just around the bearing.

But the two material wheels are always going to look better!

Kinda like tweels. The guy that cuts our grass has them on his mower.
