Anet optical z-end stop adjust

Printed in PLA, you can probably force it to fit, currently printing in ABS which requires a bit of care when inserting the metal parts. I wanted a tight fit, so its maybe best to use heat to soften the plastic a little.

This thing was made with Tinkercad (initially - then final tweeks with blender). Edit it online https://www.tinkercad.com/things/64EiCUHs7rj

You need a M4x25 or M4x30 cap screw to fit tightly within one part. Shorter will work, but you'll be restricted in adjustment range
