Prusa I3 R2 EVO Graduated Knob - Pomello graduato

Hi, this is a simple accessory, but very useful when you have to adjust the height of the printing plate in very precise way. The knob has 8 bits, and considering that a complete turn produces a displacement in height of 0.35mm, you'll have the possibility to perform a fine tuning. May be very useful to paint the major bits in different colors to set the current positions. Inside you have to insert an M3 nut, so you can block the knob with the other one to lock together to move the screw.
