After recently completing my first 3D printer (Prusa), along with Generation 7 Electronics and opto endstops, I struggled to find some decent mounts to suit my needs.
These are based on the recent Prusa Iteration 2 release with integrated m3 nut catchers.
Simple, minamalistic and can be mounted anywhere around your frame!
Print the required amount of parts.
Use a soldering iron to melt in your m3 nuts (makes for a nice tight fit!).
Mount on frame.
