My local makerspace recently upgraded from a couple of K40 laser machines to a very nice 60W Omtech machine. I’ve been helping out by doing a few upgrades. One of which is something I’ve been meaning to do for my own laser machine.
I’m always a fan of having built in adjustment tools for things that need to be periodical adjusting. Needing to use the cabinet key to open the bottom door on these bigger laser machines has always bugged me. Finally decided to design and 3D print some knobs with built in triangular key slots. Friction fit on the triangle so they can be removed if needed.
Apparently these triangular cabinet locks are not universal in the key size as the ones I made for the makerspace machine don’t fit my own laser machine. So if you make your own, I would recommend doing some 5mm tall test prints of the cylinder with the triangular holes, all the way through, to fine tune the fit size. The corners of the triangles should be slightly rounded to give more room within the cylinder.
