RC Car body Lock caps

This is a body cap. I decided to make them instead of losing the body pins all the time.
Works the same way as the Proline ones, but i made one with a 8mm washer under the cap, and one with 15mm washer. Both of them are the same size otherwise, goes on an M3 screw. For bigger vehicles you can use an M4 screw. but for this, you have to scale up the caps with about 25%.
