Nice sized dice for small kids (my 5 year old loves it for snakes & ladders).
The numbers orientation has been flipped for printing.
I did this so that the number faces would be printed face down on the glass making them shiny.
The dice itself has been oriented with number one facing down to make supports as minimal as possible. I ran through a couple of design iterations on individual number positions & orientations to reduce supports & make the design more printable. (Feedback on this is very much welcome though).
I would recommend tree supports when printing.
Once printed, the numbers should press fit into place.
