Hictop 3DP-17 SN04 Z sensor mount

A vital addition to my 3d printer. The normal method of adjusting the sensor was error prone. I decided to design my own:

Credit for the idea goes to parable, I based my design on his clever idea: https://www.thingiverse.com/thing:1534152



The main benefit is that it is compact and no sanding is required.

I believe that based on the M4 with a pitch of 0.7mm, 1mm of vertical movement would be 1/0.7=1.43 turns. So a 16th of a turn is 0.09mm.

Print both parts upside down, the "SN04-mount-and-slider-v6" stl and gcode are already done like this ready to print.

Spring, I had a 7mm x 19mm compression spring from a Rolson set 61298:

One of:
M4 x 50mm hex bolt
M4 wing nut (or print a thumbscrew)

I got the nuts/bolts from ebay:
