These three unique pieces fit together to form a box, but it's a bit puzzling to fit them together because each piece seems to be both "inside" yet also "outside" of the other pieces. It can only be achieved by bending and deforming the pieces until they can be interlaced together. Bendy Boxy Burr is an unusual marriage of a traditional three-piece burr puzzle with a common form of six-piece burr.

Interior panels follow the typical scheme of a three-piece burr, except they exploit the flexibility of the material to eliminate the extended grooves typically required for a rigid burr. Puzzle builder George Miller previously demonstrated Three Card Burr which achieved a similarly unexpected result using specially-cut playing cards.

Exterior panels are arranged in a scheme much like a typical six-piece burr, except that their movement is restricted by their attachment to the inner panels so they can't be assembled in two independent groups-of-three like a traditional six-piece burr. But the flexibility of the material permits them to be tucked under and over each other. (The schematic arrangement was inspired by my previous Cuburr puzzle, an origami-like sheet puzzle.)
