Gear-themed drawer pull knob using 1/4 inch heat-set insert

thingiverse

I designed this drawer pull knob for the clockmaker's bench that I'm building. It features a gear design on the front, and I engineered it to use a 1/4-20 heat-set insert so that it can securely screw onto a 1/4-20 threaded bolt. My tutorial on how to install heat-set inserts is available at https://youtu.be/mgcgukodNNc The Heat-Set Inserts for plastic, suitable for bolts with 1/4-20 threads: https://www.mcmaster.com/94459a370 I've also sourced the matching 1 3/4 inch bolts to fit my bench drawers at https://www.mcmaster.com/91772a548 The parts are SAE rather than Metric because 1/4 inch is a very common bolt diameter where I reside.
