Threaded Stud Knob 1/4-20

I made these to replace some that students broke on some PASCO equipment but they will have other uses.

They work well for me. I think I prefer using hex bolts rather than socket head (Allen) bolts because they are cheap and I think they will give me more torque, though I have not tested this. None of mine have broken yet.

In my application, I use a simple plastic washer between them and the aluminium part they are clamping.

There are files for hex head bolts and for socket head (Allen) bolts, both 1/4-20. Mine were 1" long but you could use any length.

I sliced with Cura and printed them on an Artillery Sidewinder X1 with the following settings and material:

- PLA (I used black from Tinkerine)
- 0.2mm layer height.
- 10% gyroid infill.
- 2 shells.
- Extruder temperature: 210 degrees C.
- Build plate temperature: 55 degree C.
- No support.
- Brim on. Though this is probably not necessary.

Assembly

- Place a liberal amount of super glue in the part I call the
