Sugar Dispensor

This small hand held sugar dispenser is designed to be held with one hand, while the other rotates a large tactile knob to dispense a 1/4 teaspoon of sugar into a coffee or tea. The sugar dispenser is 100% 3D printed, there are no other parts or hardware needed. It is designed to be printed at 40% fill density with 4 wall thickness. The design keeps most over hangs to less than 30 degrees, reducing reliance on support structure.

Please give me feedback on the design. I have not been able to print it.
