Mechanical double dice

Inspired by a model from the 1920s, I created this gadget in the credit card format. Choose the “no bearing” print profil if you don't have bearings. For more velocity, you will need for a good operation two 625ZZ ball bearings (EA016 maker's supply)(I know that many of you, makers, have them!!), and a ballpoint pen spring. The bearings must rotate without friction, so they must be soaked in a degreasing solution, and then lubricated with W40. If you want the Carbon effect, you will need the Fiber Carbon plate (effect on the photos) If you want the wheels to indicate more than six choices, let me know and I will make a design adapted to your needs: for example: one wheel with 8 numbers and the other with 20 numbers. Inspiré d'un modèle datant des années 1920, j'ai créer ce gadget au format carte de crédit. Vous aurez besoin pour un bon fonctionnement de deux roulements à bille de type 625ZZ (EA016 maker's supply)(je sais que nombre de vous, makers, en avez!!), et d'un ressort de stylo
