Incredible multiple size marker holder

This is my first design - behold its majesty! What a masterpiece of plastic imagination, don't you agree? The simple yet elegant design was created with Tinkercad for 3 different sized markers.

This incredible thing has 8 holders at 16mm Ø, 3 holders at 12mm Ø, and one holder at 27mm Ø for a fat king size Sharpie. There's even a recessed area in the center for storing paperclips, rubber bands, bubble gum, anything you like! The possibilities are limitless! Well, limited by the size of the tray but otherwise limitless!

Enjoy the thing! And may your markers never bleed or run dry!
