LowRider2 Z Endstops to Home Up

I remixed TheMaxx's remix:

of rreinier's Z axis tube bracket.

I modified TheMaxx's .stl by scaling to 101.6% in all axes to fit 25.4mm tubes and also added 1.5mm of additional thickness to the bottom that has a 1.5mm fillet on the bottom as well to match the top.  I used a M4x16mm screw and M4 locknut to secure on the Z tube approximately near the bottom of the leadscrew.

The intention is that a bracket on one tube on each side of the lowrider2 is angled out to hit a microswitch mounted to the outside of the Y plate when homing up.

I also added a custom microswitch holder to complement this Z Stop bracket that fits on front face and the underside of the LR2 Y Plate.  I designed it to be superglued to my printed Y plate but have the switch replaceable using M2x12 screws although I believe shorter M2x10mm screws should also work.  The large flat angled side is the top.  I printed it and think it came out well.  This should allow the LR2 to Z home up.  I used Omron SS-3GL13PT microswitches.

I recommend connecting to the Normally Closed position on the switches which are the outermost terminals on those switches.
