Rotating RC Car Stand/Table - TRX-4

Designed specifically for the Traxxas TRX-4 Bronco, but should work for most models in the same size range (1:10 scale). Without the ‘Chassis Tray’ part, it is designed to pick up the model from four points on the metal frame rails (see images). Although this holds the car snugly and repeatably, it's not the most robust/fastest so I added the Tray as a little more general use option. I can either be used as a static stand, by just not using the Base, or as a rotary stand by filling one of the grooves in the base with 3/8" ball bears (actually I just use 3/8" slingshot ammo, it's cheaper and sufficiently tight toleranced to work great!) The outermost groove provides the most stability, but obviously requires more balls, so up to the user.

I printed all pieces out of PLA, the stiffer material makes the turntable move easily, but a softer material for at least one of the bearing surfaces will smooth out the movement a little and make it quieter.

For my chassis tray I added a layer of thick (10mm) adhesive backed foam to the contact areas. If you are not going to use this foam, I'd recommend the ‘deep’ version of the tray to provide more clearance for the drivetrain.

Please let me know if you have any suggestions for improvements! Thanks.
