Foot for bolt and square nut (SCAD)

thingiverse

To create a rail using #6 mounting hardware, start by opening the "foot-6.scad" file in SCAD (unless you already need the exact item). Adjust totalh, totalw, and thick according to your requirements. The default settings are for square nuts and 1/2" bolt holes, but bolt size isn't limited to that. After modifying as needed, save the design as an STL file, slice it, and print it. Select a suitable bolt size depending on your PCB thickness to ensure proper nut grip. If your printer has tight holes, you may need to drill out the bolt hole. Insert the square nut, followed by a long temporary bolt to help push it in flush. Remove the temporary bolt and place your PCB on top of the bolt hole, then insert the real bolt through the mounting hole and into the nut. Tighten the bolt. The provided SCAD file also allows for creating a strip of these with different offsets or using them as feet. For easier printing, ensure the square hole points up when printing vertically. A circular version will be posted soon.
