This is my design for card playing enthusiests who like playing cards. This allows players to push the cards between players instead of reaching for a center pile. Genious! It roles in any direction! Genious!. It holds 2 decks per side with shorter walls or 3 decks per side with taller walls.

I created a screw in caster with base for fun but the base/caster without threads works fine. Walls and caster should be glued in to the base.

The only thing that needs adding is four 1" steel chrome balls from Amazon. or I have added a 3D printable sphere that surprisingly after a light sanding works pretty well.

PLA + or PLA Pro or PETG0.2mm30% infillBase no supportsCaster ball holder and walls need supportsCaster sphere should be printed less than 0.2mm.Print casters upside down so the marble hole is clean.
