As many of you I have bunch of empty filament spools as well. So I decided to design this very simple stand for my Traxxas cars based on TRX4/sport chassis. Just put this printed stand into the center hole of your empty spool and you will get rotating stand for your rc car. I don't know how about you but I was quite concerned how many times I had to lift and rotate my car during maintenance :)

To assemble the stand you will need some M3 screws. 4 to fix side walls to the base, and another 4 to fix crossbars to side walls, but these are optional and not needed.

Will appreciate any comments or ideas...
