I Made a Self Deploying Allen Key Probe To Rival The BLTouch

The hobby of 3D printing needs more touch probe options. The comparison of BLTouch vs. XYZ is kind of stupid because the vast majority of BLTouch alternatives are just clones: IP theft of the original design by Antclabs. The TouchMI is an optical touch probe at half the price of a BLTouch, but I think we can do better than that. How about 13X cheaper!?! This DIY solution uses the original touch probe idea of an Allen key activating a switch. Only this time the Allen wrench activates an optical sensor for some surprisingly accurate probing. Of course this design will only work on a Creality Ender 2, Ender3 (original), and CR10 (original) but these happen to be some of the most popular printers in the world, so hopefully lots of people will save lots of money with this awesome upgrade.

I'm working on the geometry still. It's not ready for everyone yet. Please check back later for the link to functional geometry.. ... https://www.youtube.com/watch?v=xqttz2IZ6ko
