Z Axis Fine Adjustment

An alternate version configured for an Optical Endstop can be found in link below.

I finally did it. I finally got around to making my own version of a compact z axis adjustment. The knob was created using the same knurled geometry from the MakerBot Knurled Surface Finishing Library Nut and Bolts. https://www.thingiverse.com/thing:9095 The photos vary slightly from the files (approximately 4mm shorter). Once assembled, it worked well except that the screw would turn. To prevent the screw from turning I increased the height slightly and added a hex rib inside the upper plastic part for a nylon locknut. A regular 3mm nut is used inside the knurled knob. There is also a bed leveling spring installed to maintain pressure.

Enjoy!
