Hũ vặn khóa (twist-lock) cho disk puzzle

This is a sleeker design of the jar for storing the disk puzzle in earlier printable. https://www.printables.com/model/872521-disk-puzzle-with-optional-twist-lock-box It eliminates the handle on top and uses a half-dovetail groove in the lid that is hidden when the jar is closed.

The top is unmarked, but it's not hard to close by touch. There is a wide groove that the dovetails drop into, and once in place you have to turn a little less than 44° clockwise to fit them into the tapered groove that holds the lid in place.

Note that the puzzle itself is not in this printable, but you can find it by following the link. I wanted to avoid duplication. The link also has more information on the puzzle.

This jar may be useful for storing other small items. I made it as an exercise for learning FreeCAD. I completed all my previous designs using Inkscape and Tinkercad. I used a FreeCAD revolution to combine the half-dovetail cross-section with a circular arc, and boolean cut to create the groove.
