AFX custom parts

I threw together some quick models for a few parts I wanted for my BOTAFX build...

- a RX tray for XM+ RX or anything similar size. (fits multiple frames, but is ideal for the BOTAFX)

- 2mm tall M3 spacers. Useful on any build with m3 stack bolts. Matches the diameter of typical soft mount grommets

- a bumper tube that fits in the place of a gopro on the botafx / bandolero style gopro mount accessory, to use when a gopro is not needed

- a lite retaining ring for small capacitors such as the 35v 330uF capacitor that ships with the Talon Gigawatt ESC

These should all be printed in TPU.
These are quick designs and may be updated in the future.
