Brompton 3-part Easy Wheels

I took some inspiration on the original Brompton Easy Wheels, and also on other models I saw around the web, but designed this one from scratch. They are intended to be instaled using the original parts on the standard roller (12mm tube, shim and screw) Print the tires in TPU, and the 2-part inner rim in PETG, ABS, ASA, etc… I don't recomend PLA, because sun and heat will eventually deform it. After you print the parts, place the TPU tire on one of the rigid parts, and carefully align the other one and apply force to join them. If you need, gently use a small rubber mallet, but don't knock on the center - use a ~30mm tube or bump carefully around the edges until it all falls into place and lock the tire.
