Metal Socket Holder Caps

This is just a simple design I made for End Caps to my Socket Rail Organizers from Harbor Freight. These are the cheap socket holders that work okay but all have one fatal flaw. They socket holders themselves like to slide off the rail. This cap helps prevent that. In addition, this cap also provides a less sharp edge as a bonus. It is recommended to print these out of TPU as that will hold up to the wear and tear or auto repair. I would not recommend any other plastic as the part was designed with TPU in mind so clearances are not 100%. I also included a bolt and nut hole. This was designed around a standard M3 nut and for my application works well with an M3x5 button head screw.
