X and Y limit switch / end stop mounts for 3018 Pro CNC router using the [Genmitsu style PCB switches as seen here](https://www.amazon.co.uk/gp/product/B08P1D6WTR/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=B08P1D6WTR&linkCode=as2&tag=tl0d-21&linkId=3442842fc923b28f44123e8eb2fe3692). Includes OpenSCAD files in case you want to remix or adjust the dimensions, but the versions here have been through a few revisions and are now working great on my machine. The Y limits work by mounting the switch to the 20mm T-Slots at the sides and inserting the printed peg into the end slots of the 15180 mount plate to press the switch down. There is no loss of travel for this. The X limits work by mounting to the 20mm T-Slots behind the spindle carriage - one above and one below. The spindle carriage itself will press the switch. You lose about 15mm of travel at each end with this, it's something I'd welcome a patch for. UPDATE 16/06/21: added Z limits. The Z limits work by removing the z-stepper and inserting the print onto the standoff pegs. The moving part of the spindle carriage presses the switch directly. There is no loss of travel.
