Playing Card Tray with Caster Wheels 3D print model

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 PETG 0.2mm 30% infill Base no supports Caster ball holder and walls need supports Caster sphere should be printed less than 0.2mm. Print casters upside down so the marble hole is clean.
