Attached you will find a small collection of 3D printable parts I have found useful when building or asembling enclosures. I have a board-mounting block, handy in situations where the PCB mounting holes aren't quite where you want them; a foot (I use peel-and-stick felt dots to cover the hole and prevent scratches), a couple of knob designs, and my version of a coax stripper that uses utility blade cutters. The knobs are a little unusual because I didn't think the plastic would be robust enough to avoid stripping-out the set screw threads. I got around that by using a short length of brass hex stock. It's drilled on one end to accommodate a pot or switch shaft, and drilled/tapped on the side. The hex piece is glued to the knob to fix it in place, and the hex form adds additional strength, in terms of torque. Pots are pretty easy to turn but switch shafts can require more torque to turn them.
I also like the visual appearance of the brass, but it would be easy enough to print a blind hole if you don't want that look. I'll add an STL of one with that feature to this thread.
The only tricky part about assembling the knob is keeping the glue away from the set screw hole. A drop of CA glue will do the trick.
