Knurled Knob for 1/4x20 nuts and bolts.
I really like the feel and grip of the knurled knob, and it has a smaller footprint than wing knobs. This is perfect for woodworking jigs that use T-track
1" outer diameter, fits the 7/16" head on a standard 1/4"x20 nut and bolt.
Designed for a tight pressure fit. You will need pliers to insert the nut.
I printed with 3 shells and 20% infill for some extra strength.
