Puzzle geometry

Working on figuring out what offset works best for puzzling together some plywood. Figured I’d share in case anyone else could use the info!

-0.1mm will go together but probably never come apart. No room for glue.

-0.2mm fits tight but can be disassembled. Good tight joinery.

-0.3mm fits well, would be good for tiny adjustability and room for glue

-0.4mm fits loose, not good for joinery. A touch too tight for actual puzzles

-0.5mm fits loose. Perfect for puzzles.
.
Not a tutorial Size and complexity of the joint geometry will change these results. But hopefully it can be a good starting point.

Thank you for sharing this. Clear and to the point, and the examples were helpful in order to better understand the differences.

Yes will be helpful for many users and I can be testiment to the fact if it’s to tight it does not come apart.
Experimented with a thingyverse 3D reindeer and it won’t come apart with out a hammer!

excellent, thanks for sharing. Best information always comes from the end users.
