T-slot nut side approach

thingiverse

I used T-slot nuts with side approach to mount my power supply mod on the Ender 3 pro's aluminum profile, making it significantly stiffer. You can normally use the four holes, but tapping a thread is required. For lighter applications, these nuts will work just fine. Don't rely on them for structural purposes. I haven't thoroughly tested their strength, and I suspect that different print orientations and more abrasive materials like Nylon with carbon fiber could increase the pull-out force. In my case, I printed the ones you see in the picture using PETG, which is relatively smooth, and was able to remove them by hand easily. If these nuts prove useful for other projects, it would be interesting to explore ways to boost their pull-out strength.
