This is a variation on the 2x4 Fidget cube. This is one of my most popular 3D prints, it is amazing how many people like this. It can also be a baby toy. No assembly required. Recommend you print with support from the base plate only. There are some overhangs that I might be able to do something about, but for the most part it prints, then a little bit of cracking sound as you bend it the first few times, and then it is very smooth. I designed this in OpenScad because I wanted to add text to the cube. If you don't have a dual extruder then simply set the textFill to 0 and the text will show up as an indentation on the cube. If you don't want any text then set the textFill to 2. textFill to 1. Text means this can be used as a promotional give away, or an advertisement. One neat thing about the text is that the part of the text that shows up on the hinge pins will always be correctly oriented when the cube is in the correct orientation. Capital letters and short text are recommended as the gaps between the cubes can make the text difficult to read if it is too small.
