I’ve now printed two of these and my wife says I will have to print more. 5 stars because this is fully functional. I would make some suggestions though: consider making the puzzle piece simply a cutout (hole). I think it would look better than the bridging which can look stringy. Changing the hinge to have a hexagonal cross section on the outside would also remove the overhang at the print bed.

Works great! I think the brim was overkill, but it came off easily. Printed a second one at 1.5x for some wide mouth bottles.

Printed in PLA Glow. Came out awesome.

fits great
