7/8 inch tube clamp for diy music stand

thingiverse

I was making a music stand from whatever materials I had lying around, which was 7/8 inch diameter tubing and m6, 1/4", and #10 screws and nuts. I used someone's scad file to make knobs for hex nuts that were 10 and 11mm wide at the flats. 7/8 inch is a common diameter for broom handles or 3/4" copper pipe in the US, my tubing was from an old bathtub/shower shelf unit. customizable hex nut knob: https://www.thingiverse.com/thing:714498/files
