Here is a model of a roulette-style dice. This will save a lot of people from dropping the dice!
Thanks to the magnets there is never any ambiguity since the die will always stop completely on one side and never straddle between two numbers!
This model requires 2 type 608ZZ bearings: https://fr.aliexpress.com/item/32722213687.html?spm=a2g0o.order_list.order_list_main.5.64d65e5b66KNA1&gatewayAdapt=glo2fra
