F1 Ultra Bottle Opener Keyring Jig

A simple full-plate jig to hold anodized aluminium bottle opener keyrings for the XTool F1 Ultra laser engraver. You can hold 18 keyrings upright or upside down. Theoretically you could hold 36 in mixed orientation, but as the engraving heights are different it wouldn't be much use. I printed this in PETG as that's what I had to hand, but it would work fine in PLA or any other filament you have to hand.
