Huey Z-adjust.

thingiverse

Note. Slight error in first upladed - fixed. I've tried several methods for adjusting the Z micro switches on Huey. This works pretty well. Rotating the disk gives 2.3mm of adjustment for the micro switch. Huey has 4 Z switches but most printers don't. The main mount will be useless to everyone else but this stepped disk maybe of some use to others. Instructions The steps are .1mm so obviously you need to print it will .1m slices to make the most of it. Slic3r did funny things at .1mm and I had to set it to have every layer solid.
