T Slot Hex Bolt Knobs For Router Table Or Cross Cut Sled Jigs. 1/4" and 3/8" sizes

Rather than spend a bunch of money on Aluminum T-track for my table saw crosscut sleds, or my router table, I opted to cut my own tracks. I purchased some t slot bits online - https://www.amazon.com/gp/product/B08DCN3NBV/ that cut a groove for either 1/4-20 Hex Bolts, or 3/8-20 Hex Bolts. Accordingly, I decided to print my own knobs so that I could tighten down the bolts easier.

Just place a small dot of superglue in the top of the knob, insert the nut, and you're ready to go and have saved yourself a nice chunk of money.
