After completing my ET48 2.2 basher build, I noticed it was missing a few minor details. One of these is a skid plate to protect the body from scratches. After unsuccessfully searching the internet for a model I could 3D print or buy, I decided to design my own. It isn't much, just a 100x100mm square that is hollowed out with four countersunk m3 screw holes and a non-countersunk side that goes on the inside of the body to give it some structural integrity. It isn't necessarily the best design because it is one of my first designs, but it works. I'm posting a Thingiverse link for anybody with a 3D printer interested in having one of these on their car.
