Small thumbwheel for bed leveling

cults3d

Small 18mm thumbwheels replace manual bed adjustments on various i3 kit printers. These thumbscrew nuts and wing nuts are smaller, but won't bump into anything. An M3 screw has a 0.5mm thread pitch; every full turn of a bed leveling nut moves the bed up or down 0.5mm. Two turns would be a full millimeter. The thumbwheel I designed features ten points, so every point represents a 0.05mm height change. Two points move that corner of the bed up or down 0.1 mm. I created another thumbwheel design too large for some newer i3 kits.
