Key/Wrench for Adjustable Spool Holder

v3 Update: based on feedback I've increased the tolerances on this model. also working on an alternate version to make it easier to visually align the key.

Used the original model as a blank to create this key/wrench to help with removal of over tight spool inserts.

Recommend printing two of these right away, but might get away with just one.

I have at least a dozen of these that never gave me an issue, but then had one get stuck on PETG-CF spool. Probably left it on when it put in the dryer once, but this tool popped it off even so.
