I've been building a modular synthisizer (with 3d printed panels) and need to quickly tighten a lot of jack sockets and potentiometer nuts. So I whipped up this little 10mm/12mm wrench that lets me do it.

2/10/2021 - Added a modified .stl with 12.5mm/8mm wrenches as the latest set of phono jacks I got came with slightly larger nuts and 8mm is useful for the nuts on small switches.
