I build this dice after a model from Viennas School of the Blind. Version "wuerfel" is the strict model, but is rather hard to print, you need 2 component print at least. Version b1 is made to easily print everywhere, just place the dice that number 1 is on the plate. The 1 on the dice is different than the other sides, thus making it easy to identify.No rafts or beddings needed.
