Knob for M6 Squared off Bolt - Tall and Wide

I needed some large knobs for some simple hold down clamps. This knob is tall and wide so you can really crank down the pressure.

I printed mine in PLA with 50% infill and it is really strong.

It is designed to fit an M6 bolt. I had countersunk internal hex bolts. To make them grip the knob (and fit) you have to cut down the head. just cut off two opposing sides.
