Rubik's Cuboid 1x1x2 - One Piece

thingiverse

Here are the instructions: Create a 1 by 1 by 2 Rubik's cube using a single printed part with no assembly needed. To do this, first model the cube in Autodesk FormIt 360 on Chrome. Next, print it on a Makerbot Replicator 2 using the following settings: set infill to 15%, add rafts and turn off supports; use a 0.20mm layer height, with 2 shells. Once printing is done, remove the raft, give the cube a twist and pop out the small support piece inside the hole. Finish by adding stickers, which should completely cover any openings you left.
