No. 70 · 8 cubes on 8 pin hinges, endlessly foldable, print-in-place – print file
4.75 – 2 pieces of feedback on the shop (not verified)
Eight 20 mm cubes hang on eight pin hinges and can be folded over and over in the same direction: cube, flat plate, tall plate, cube and so on. Everything is made in one print.
The print position is the flat unfolded layout (2 × 4 cubes). Two hinges each sit at the top in the middle and at the top ends, four stand vertically on the outer edges. No hinge lies on the print bed. The folding sequence has six positions (two cubes, four plates) and then starts again.
Each hinge has a 2.6 mm diameter pin in a 3.44 mm hole; the hinge eyes have 0.4 mm of clearance to each other. All cube edges are chamfered at 45° so the hinge eyes have room in every position. The whole cycle is calculated in 78 positions with no parts touching.
Snowflakes and stars are embossed 0.6 mm deep into the cube faces.
Print notes included in German; part names are self-explanatory.
