Knob for M5 threaded rod / stud

thingiverse

This is a knob intended for use with any M5 threaded rod or M5 stud. I designed this to use with my Shapeoko / Xcarve that has been upgraded with a T-slot bed. I needed a way to hold my hold-down clamps using M5 studs, and I couldn't find any M5 knobs I liked that had a thru-hole for the stud. To use, print flat side down on the bed. Clean out the nut socket with an x-acto knife or similar, then press a standard M5 nut into the nut socket. I used a M5 screw from the back side and a washer to pull the nut into the nut socket. It's a drafted hole designed for a snug fit so the nut stays put once it's pressed into place.
