Z Lock Key with Tag

Ever been working on your (alum. extrusion) printer and had the Z axis inadvertently slide down? Yeah, me too.

Place this twist-lock key in the slot in the upright and it'll keep it from sagging while you're working! It holds pretty well. I am probably going to redesign it a little here and there, so I'll keep this as a WIP for now.

Enjoy!

Special thanks to Prospect3dLab for the great looking 'Remove before flight' tag.
