This model has 0,4mm tolerance. If you need less or more tollerance let me know in comment, i have project with parametric design so can add any tollerance. On pictures you see 70% rescalled print (black cube). For best results I suggest using paint-on supports as last picture showing. The black one was printed with 0,2mm layer height, but for such small print 0,1mm should be better. Blue one is 1:1 and 0,1 layer height. It's nice stress test for your printer. Enjoy!

this is how it works :)

I suggest do not print it at less than 70% scale. At 50% it will be too fragile and last not so long. I found out 70% is the best for one handed use.

Please print it with at least 4 perimeters, hollow will break real fast.

I'm uploading sturdy version of cube. It has thicker hinges and built in supports. It can be printed nice without additional supports. Built in supports should self remove after first moves.
