So I twisted my phone cover onto the mount in my car. Unfortunately, it wasn't properly seated, so the cover got locked in the wrong position.
The case comes with a stand tool, but I had misplaced mine, so I designed this 3D printable replacement instead.
I printed mine in PETG, but you can print in whatever material you like. It'll be strong enough.
I included the g-code for both PLA and PETG on the Prusa i3 MK3S+.
