Stud or Captive Nut Knob - 3/8"

thingiverse

I required a 3/8" studded knob for a project recently, but couldn't find one that met my requirements. I designed this multi-function knob to be used as either a stud knob or captive nut knob. The cap covers the screw head when used as a stud knob and can be excluded for use as a captive nut knob. * Note - Using this design reduces the length of the screw by exactly 1/2". I printed the knob at .2mm layers using Proto-Pasta Carbon Fiber PLA, while the insert cap was printed at .2 with Verbatim Green PLA. The Verbatim Green is similar in color to Festool but I actually prefer it slightly better as it's not quite so lime green. No plans exist for creating this design in any other size; however, I will create others as needed and share them when available. Special thanks go out to airald for the inspiration behind the insert.
