Music Stand Clamp Knob

thingiverse

I was given a broken knob for the clamp on a music stand. The bolt had shattered out of its plastic casing. I came up with a solution. The hex hole in the knob fits perfectly around the bolt head. The hex tube slides down onto the bolt and both are pressed firmly into the knob. I drilled the hole slightly larger to make it easier for the bolt to fit snugly inside the tube. Before assembling everything, superglue is applied. This seems to be a decent fix.
