UniversalProbe for AutoBed Leveling

This is a probing system, I use it to auto level my bed using some aluminum tape that I bought at walmart attached to the base the aluminum foil has a ground connector to it and the top lock has 4 screws which run the positive. These are wired to the z min endstop and the usezendstopasprobe setting in marlin is enabled along with autobilinearleveling. I then wrap rubber bands around the top lock and around the side hooks. I have obtained about a .0138 accuracy for repeatability tests over 7 different tests total so it's more accurate than my motors can be at the moment. I am using a cheap chinese gt2560 with the ATmega 1280 on it. Feel free to contact with questions!
Hunt down my youtube next level jank for more information!
Hope this helps people!
