I picked up a track set a while back for some Mini 4wd-compatible cars, and it came with a few of these Bandai "Super Hyper Racer" 4WD cars in varying stages of completion and condition. The assembled cars were both missing the clip that secures the bodyshell to the chassis. There was also a mostly-unassembled car with a clip still like new on the sprue, so it was simple enough to replicate.
I printed two of these in ABS. Without changing any settings, the first required some finessing with a blade and drillbits, while the second fit perfectly right out of the printer.
