I made hexagonical version of do nothing machine. It is custom build designed by me, it uses the same mechanics as the original machine (some angles, coridors, etc.). Can be printed on almost any printer at any size, looks good when different colors are used for different parts. I printed it at 50% size so it fits in my hand. I recommend gluing the pins to the slider so it wont come off in the middle of spinning. It was designed in onshape.
