An OpenFab original! The RaceBox is a 3D printed die-cast car carrier with a hidden secret. Open the lid, remove the cars, and lock the handle in place to make a ramp for jumping and racing! The handle uses rubber bands for friction…or are they for something else? There’s a hidden Easter egg function!

My three-year-old son provided the inspiration for the RaceBox. There are two versions: full and mini. The full holds four cars and the mini holds two. The CAD files as well as the printed products are for sale on Etsy. The STL files for the Mini are free on Thingiverse.
