I think it's a fun idea but I want to caution here. The seams between walls are not tight enough, and not inflexible enough, to keep the beads inside. Getting beads out of the AMS is not fun and there is some risk of the beads going places where you dont want them. So, an interesting concept that needs another iteration in my opinion.

5 stars for thoroughness and overall consistency of design. The big box is a little bendy at that size and the lid tends to hit the cards on the way down. I created a small guide, and glued it to the internal sidewalls, to center the cards so it doesn't happen.

I really like the design and I'm impressed with how stable and solid they are. Ultimately, they are a bit too small for my purposes but that doesn't at all detract from them fulfilling their function as the creator wanted it, and doing it well.

no issues beyond the red pins not “friction fitting” in the base, meaning they are very loose. Everything else works fine and is fun!

no issues at all, everything printed easily and was easy to combine afterwards, though maybe a hint or two to the best order would’ve been nice. Thanks for giving it to the community.
