This is the CAD files for the RaceBox Full and Mini and their handles. The Full fits four cars, while the Mini fits two. Both are awesome! The RaceBox is a die-cast car carrier with a twist. Take out the cars, snap the handle in place, and you have a ramp for racing and jumping!
These models print well on most well tuned FFF style 3D printers that are large enough. Sizes are:
The RaceBox is 169x198x45mm.
The RaceBox Mini is 89x198x45mm.
The handles are smaller.
Files for both versions come as STL and STEP. STEP files may be better if you want to make edits. STL files are what you need to 3D print. All files are zipped into a compressed folder.
Files updated 3/12/18: Fixed a missing fillet on both Mini and Full sizes.
