I needed a mini-clamp to hold down my spool holder to my desk and mistertech's design was just about what I had in mind, minus the headphone part. I also shortened the clamp down to 20mm because my desk is very thin. I also wanted the screw to withstand more tension, so I decided to split the original model and print both halves horizontally and acetone weld them after.
If you want the whole bolt or a larger version, check out the original design.
Rafts: No
Supports: No
Resolution: 0.2mm
Infill: 30%
Acetone weld
With a small paintbrush, cover the flat surface of each screw half with acetone. Quickly, before the acetone evaporates, align the halves and hold together firmly for a few seconds.
The author remixed this model.
