i3 Clone Z Limit Switch Bracket

Replace the always moving Z limit switch bracket with one that stays put. The aluminum prototype was made because I was not printing yet due to the poor Z limit switch bracket. I made a left hand and right hand version. Can be mounted either up or down as needed to get the limit switch in the correct position. The holes are sized for reaming after printing. I used 3mm x 10mm screws to fasten to the 2020 and 2.5mm x 25mm to fasten the switch on.
