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 :)
