1/4-20 Knob

This is a knob that I designed and printed to hold a 1/4-20 nut captive. I use these in the t-tracks and miter slots on my bandsaw, router table and table saw. It's a "through" design, so the bolt can go all the way through the knob as you tighten. I was able to use the preview in my slicer to locate the layer in which i needed to pause. For my printer, inserting an M25 in the gcode just before that layer did the trick. It pauses and docks, allowing you to drop the nut in and then continue printing. The pause code will vary depending on your printer.
