I remixed the original design for the Atomstack A5 pro limit switches for the following reasons:

• I wanted to mount the switches without damaging the rails
• I wanted the X-axes to be adjustable
• I had limit switches with the lever on the other side
• I wanted them to be easily printable

The x-axe snaps on the rail and can be fixed with a t-nut (thanks to https://www.thingiverse.com/thing:3050607). The X-holder can also be used in any other orientation or with microswitches with the lever on the other side.

The y-axe just snaps on and holds itself in place.
