Tiny Touch (the smallest DIY Z-probe) for Anet A8

thingiverse

**Update 5 May 2020**: [MK3 is now available as a different thing](https://www.thingiverse.com/thing:4328025). It's a complete redesign. **Update 15 Oct 2019**: After making and using tiny touch for awhile now, I’ve noticed that the M3 bolt that screws into the flag is a design flaw. At some turns you may screw it not straight in thus it may snag on the hole. I’ve redesign the body and the flag so the M3 bolt and cap are no longer needed. Here’s Tiny Touch MK2, I have updated the build guide to reflect the MK2 changes. --- **Quick Update**: - Added youtube clip of it in action: https://youtu.be/RZY6Nvi4sqs - M48 results ``` Send: M48 Recv: M48 Z-Probe Repeatability Test Recv: Finished! Recv: Mean: 0.022500 Min: 0.000 Max: 0.040 Range: 0.040 Recv: Standard Deviation: 0.009487 ``` --- The main difference from the original is that I made the body a bit bigger. Maybe because I print ABS and there’s shrinkage. And i flatten the top part, again, because I can’t fit the optical endstop flush to the back. And I added 1mm easy to break-off support for the overhang. Complete step-by-step guide now available on [my blog](http://soemarko.com/blog/tiny-touch-the-smallest-diy-z-probe-for-anet-a8). After you made this, I highly recommend replacing the spring bed mount to a [solid bed mount](https://www.thingiverse.com/thing:3852796).
