This is a storage case intended for use with Crayola Large size Crayons. These Crayons are approximately 12mm in diameter. This case holds 16 Crayons, and the lid has mild retention to keep it from falling off unintentionally, but still easy enough for a small child to remove. I have designed it to print support-free, and to allow the continued access of the Crayons, even when they wear down significantly. I have given the Crayons a small amount wiggle room side-to-side in their tubes to allow for manufacturing variances, and generous wiggle room vertically.

Happy Printing!
