Prusa Mini Z-Axis foot Easy install!

Improved version of Loewekordel's very helpful Z-Axis foot for the prusa mini! 

One simple modification added to the original:

• Screw port for easy installation and removal

Uses the spare foam pad included with Prusa mini. Could also use other foam cut to size.

I was having a difficult time installing (and an even more difficult time removing), this Z-axis foot. I thought this was a worthy upgrade.
