Key for Creality SpacePi Space Pi X4 Compact Spool Auto-Rewinder Mod

The key is designed to make it easier to unscrew the nut from the "Creality SpacePi Space Pi X4 Compact Spool Auto-Rewinder Mod" project. I had problems unscrewing the nuts. They were difficult to loosen, and the grips are very narrow. Using the key solves this problem. 🙂
