Z Height Adjuster - For Rock Solid X Axis Prusa Mount

A clamp on Z Height adjuster for use with my Rock Solid mounts.

You need:

2x M3x25 Bolts
2x M3 nuts
2x M3 washers
1x small coil spring (nominal 3mm ID)

Notch in the dial so you can quickly see if Z height has shifted, or calculate no. of turns. With M3 bolts 1 turn is 0.5mm which is convenient.
