3018 Pro Z axis limit switch

This is a remix from https://www.thingiverse.com/thing:3663872 setup to work with a stock spindle holder.

The top bracket attaches under the Z axis stepper motor.

The bottom bracket may be glued or taped in place with two-faced tape. Carpet tape works pretty well.

The switch holder may be taped in place with two-faced tape, or is setup to be screwed to the spindle bracket after drilling holes. A drill guide is provided as well.

All fasteners are M3
