These tiny objects are NOT real chairs! It's a classic mechanical puzzle from ThinkFun:

Fit four chair-shaped pieces together to form a single, large chair. Easy print, easy puzzle, enjoyable for everyone. Try it!

It's the #1 item on “starter set for a new collector” of Rob's Puzzle Page. Sadly for me this item is not that easy to collect. Luckily I saw a demo on TikTok and figured out its geometry. It turns out working nicely.

I recommend print the chairs in “side-lying” position to hide seams, as shown in .3mf file.

Happy printing & puzzling!
