12mm/10mm finger wrench

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.

Print instructions

I printed it with the 12mm side down and supports. Would probably work without supports...but this helped it come out a bit cleaner. I just printed it on 0.3mm Draft on my Mk3s since I wanted it quick. Works great!

I've also printed these in Sirya Tech Blu on a MSLA printer and they've worked great.  For SLA I put them at an angle and used supports - probably would have worked printed vertically but laying it over made for a much quicker print and still seemed to maintain dimensional accuracy.
