Abalone Ball Container

I recently bought the game Abalone and the cardboard box for the balls didn't last very long and since, the balls were rolling free in the whole box.On research I found that this is still an unsolved problem for many users.I couldn't find a proper printable solution, so I got creative. The model contains:A container for 14 (2 * 7) balls with a diameter of 25mmThe lidA bolt, to lock the lid onto the container You need to print the model twice, to cover for all 28 balls of the game.I printed them once in white and once in black, according to the ball colors. I put felt pads (25mm diameter and 5mm high) on the bottom in the container and on the lid. The lid and the container contain holes for the bolt.After filling the balls into the container, you may need to press down the lid to be able to insert the bolt.
