Hello! These jank looking dice are mathematically true and fair.
The majority of work and documentation can be found over at Carlos Luna's page. I just wanted to bring my profiles to MakerWorld for the ease of clicking print and letting it do it's thing.
This is a direct copy of https://www.printables.com/model/616349-skew-dice but with my own print profiles.
I dealt with a lot of spaghetti and adhesion issues whilst trying to print these (not sure if that's to do with the latest firmware update or what) and have settled on a print profile that ends up printing nice looking hefty die with the use of supports.
