I upgraded the CPU of my Cetus Mk2 with a Tinyfab CPU (https://www.tinyfab.xyz/). That meant I had to add some end stops. Fixing them with hot glue worked well as a temporary measure, but something more permanent was in order after it came loose the first time.
Uses M2.5 threaded inserts to make the screw connection of the switch rock solid.
Edit: Turns out one of the screw heads interferes with the print head carrier. But cutting off the head and just using it as a registration bin works just as well.
