3D-Printed Tools Turn Bench Vise into Expedient Press Brake
https://hackaday.com/2020/01/06/3d-printed-tools-turn-bench-vise-into-expedient-press-brake/
Chances are pretty good that most of us have used a bench vise to do things far beyond its intended use. That’s understandable, as the vise may be the most powerful hand tool in many shops, capable of exerting tons of pressure with the twist of your wrist.

If there’s one thing that gives us joy here at Hackaday it’s a story of audio silliness. There is a rich vein of dubious products aimed at audiophiles which just beg to be made fun of, and once in a while we oblige.
