About this model

Simple bed leveling knob for Maker Select/Duplicator i3 and similar printers. I found that with other knobs I often got the up and down directions mixed up when adjusting the level on the back screws and had a hard time getting a good grip. So I designed this version that helps differentiate between the directions a bit. It also allows you to adjust the level with a single finger which can help when reaching around to the back of the printer. An m3 nyloc nut should be used with this part. In the picture you can also see a two part spring guide I have also uploaded to thingiverse.
