Spektrum DX2S/DX3S Wheel Donut

thingiverse

Outer donut/wheel for a variety of Spektrum DX-S series radios (DX2S/DX3S). This may fit some others as well (I have not confirmed). The original foam donut works OK on the radio, but over time it does become looser. For a radio of this age, it likely has become loose. I also prefer a rubber/TPU wheel for better grip. To install, unscrew the center wheel and pull it off the transmitter shaft. Pull off the foam donut and replace it with the TPU printed version. NOTE: This is intended to be printed in TPU. It may work in a non-flexible material, but the dimension for the inside would need to change for it to fit properly. This is intended to have a very slight interference - but assumes that you are printing at a pretty high flow rate so if you print this and it is loose, change your settings to a higher flow rate to adjust or modify the model.
