Summary The stock HICTOP Prusa i3 3DP08 Z endstop switch is held by a 2 piece acrylic that doesnt provide vertical stability or minuscule adjustment. I made this in order for me to be able to make minuscule adjustment to the Z Stop switch while keeping the switch itself straight. Adjustment is from a M3 x 40mm bolt, and a M3 locking nut on the right side of the part. Print Settings Printer: HICTOP Prusa i3 Rafts: No Supports: No Resolution: 0.3 Infill: 10%
