Accepted! To be fair I’ve already played with this a bit. I wasn’t comfortable using them with a clamp where the surface the nut would hit wasn’t level. It forces the bolt to bend because a plastic T-nut has to fit tighter than a metal ‘toilet bolt’ in order to be strong enough. My first attempts also used vertically printed bolts. They were pretty strong though, I kept tightening the nut until one broke and the bolt/nut flew up and hit the top of my enclosure 3.5’ up. So I think it had a fair amount of tension when it broke!
Anyway these were printed with the bolts lying down for increased strength. Printed with PETG through a 0.4mm nozzle. I needed to drop the nozzle from 0.6mm in order to get decent threads.
The zip file has the T-nut, who knows if it fits anyone else’s T-tracks, the top nut, a vertical 100mm bolt, a horizontal 100mm bolt, and a 30mm tap that was used to cut the threads in the nuts. With the tap you can design your own T-nuts if needed and the bolts can be trimmed to length in your CAD software.
If anyone needs to make Nuts and Bolts and your CAD software doesn’t have them you can try my OpenSCAD library. It comes with a PDF that should get you going with OpenSCAD if you’ve never used it before. The library uses the ‘customizer’ which is a graphical user interface that allows you to change values and make different parts without messing with code.
