MP Mini Delta Endstop Calibration Block

This design is a tool used to calibrate the optical endstop sensor locations on a Monoprice Mini Delta printer.

This design is for those who need to replace an endstop sensor, or who are having issues achieving a level first layer on their prints. If you are using this tool to solve leveling issues, I recommend first following the leveling recommendations on the wiki page https://www.mpminidelta.com/start before attempting, as the use of this tool requires an moderately extensive teardown of your 3D printer that could lead to other issues if not reassembled correctly. Disassembly may also void your warranty.

I also recommend the installation of a glass or mirrored bed plate to take full advantage of your leveled endstop sensors. After using this tool, I was able to print directly on a mirrored glass surface without the use of adhesives or rafts.
