Pentomino Twisty Puzzle

thingiverse

UPDATE 6/21/18: I designed a second version of the centers, incorporating screws instead of pins to make them more secure and less prone to falling apart. To create v2, do not print "center_x2.stl" and instead print "center1_v2_x1.stl", "center2_v2_x1.stl", and "center_cap_v2_x1.stl". This puzzle isn't a traditional pentomino in the mathematical sense. I chose the name because it's the pentagonal equivalent of the 3x3x2, or Rubik's Domino. Thus, it is a "pentagonal domino". The name is a portmanteau of the two words, hence "pentomino". A fully functional 2-layer pentagonal twisty puzzle has been created. It is the pentagonal equivalent of the 3x3x2. The 2x3 faces can turn 180 degrees, and the pentagonal faces can turn 72 degrees. To make **v1**, which doesn't use any screws but is more likely to fall apart, print: * 2 Centers * 10 Edges * 10 Corners * 1 Pin To make **v2**, which uses a screw but is more stable, print: * 1 Center 1 v2 * 1 Center 2 v2 * 1 Center Cap v2 * 10 Edges * 10 Corners V1 of this puzzle utilizes a flexible pin mechanism rather than screws, so it's fully 3D printable and no extra materials are needed! Stickers for the 2x3 faces are standard 57mm 3x3 stickers. The top and bottom stickers can be cut from the sticker template.
