TPU wheel and PLA hub w/bearing. Designed and used on an Eflite Night visionaire, but should work on any 3mm wire landing gear. Uses these bearings ( uxcell F623ZZ Flanged Ball Bearing 3x10x4mm Shielded Chrome Steel Bearings 10pcs: Amazon.com: Industrial & Scientific ) from Amazon. Or probably any 3x4x10mm bearing. Used a couple of drops of CA glue to hold the bearings in and more CA to hold the hubs together and to the tire.

Overture TPU and Overture PLA. Wheel printed at 30% infill, with support. Hubs printed with supports also.
