About this 3D model
If you purchased a MendelMax 2.0 hardware kit or you are building one from scratch you may not realize the original design was for a Cheap-O magnetic endstop. If you favor optical endstops and have purchased a RepRap OptoEndstop, this kit is what you need for your MM2. I designed this mount similar to the Cheap-O so that you can simply use the provided hardware in the kit.
