Z-Axis Alignment Endstops, 20 mm extrusion

I made these for mechanical Z-axis alignment on an SV01 Pro, but they'll work on anything with a 20 mm aluminum extrusion and T-nuts. 

There are versions for M3, M4, and M5 screws. Intended screw length is 10-12 mm. You'll need T-nuts (printed or purchased) of the same screw type to install.

Print Recommendations:
PETG, no supports, 0.4 nozzle, 0.2 mm layers, 3 wall lines, 20% Gyroid fill.

At 60 mm tall they may cut a tiny amount of print height, but I don't really consider that usable height anyway due to the way the cables and filament are routed.
