Instructions
Print with some slippery plastic that is a little soft (like ABS).
This doesn't have a hole for a set screw, but the hole should be tight on M8 threaded rod, and the beveled edges should help get it started. Carefully screw it on while trying to keep it level. Only screw it on until it is tight, not all the way... the plastic should be threaded by the rod as you tighten it if it is soft enough.
Use it to manually raise your Z platform high enough that you can make sure everything clears and it will never hit anything during build.
