I see someone did this for their 1610 CNC and the parts are in thingiverse.
This is what I added:
After having fun drilling 2mm holes and using M2.5 hex head screws I did the same for the X stops and mounted the switches.
I set them up so the whole drill assemble when moved on the X axis towards an end stop will trigger it.
The Z switches I need slightly longer arms on the switches, or will have to add something to the bed to switch it. Procrastination time needed. Use slightly longer screws and lock nuts too.
I also added some nice new 8x5 bearing couplers too. The one on the Z axis looks fine for now but might take it apart and replace.
