Permanent Oppener ACE PRO

Unfortunately, some manufacturers supply filament in spools that are impossible to use with the Anycubic ACE Pro. They are too large, and when the door is closed, there is no space for the filament to unwind. But there is a solution: work with the ACE open. Leaving it fully open exposes the filament. To make it partially open, I built this very simple model that fits into the ACE's "lock" and allows a small opening of 12mm (about 1/2 inch), more than enough space for the spool to roll freely during printing.
