THE ULTIMATE JIG KNOB
Working in the garage, I often find myself setting up jigs using 80/20, T-slotted channels, fabricated Aluminum brackets and 3D printed parts.
In the past, I always found myself needing more knobs. I used Pronged T-Nuts for a while but I really wanted a universal knob that I could use for all my projects.
I set about designing and refining these Knobs to maximize their flexibility. Early designs were too smooth, so I added knurling. Knobs sometimes needed to be tighter than I could hand torque, or became stuck, thus the hex shaft. Starting the knobs was a pain, so I designed a simple tool to socket in the back of the Knob.
I've come to love this design, and I hope these knobs find their way into your shop!

Use support touching buildplate.
NOTE: YOU NEED TO TAP THE TREADS TO GET A STRONG THREADFORM.
