About this 3D model

These are some of my twisty puzzles (or more commonly known as Rubik's cubes). These include: A 1x2x3 which you can put stickers on (black) A bumped 1x2x3 which you solve by shape (yellow) A split 1x2x3 (also for stickering) which can do 90 degree turns. It can also be thought of as a bandaged 2x2x3 (green) And a bumped split 1x2x3 which, again, solves by shape (blue) All of theese are print in place and are printed with the largest face on the build plate These range from incredibly easy to pretty hard to solve with the easiest being the normal 1x2x3 and the hardest being the bumped split 1x2x3 (I couldn't solve it.)
