My problem is I have trouble putting the perfect amount of toothpaste on my tooth brush. The problem is located in the bathroom of my house. This is a problem that I need fixed so I can improve my mornings and nights by being able to put the perfect amount of toothpaste on my toothbrush fast and efficiently. I believe the 3D printer should have no problem making a device to help with my problem. There is no certain color that my 3D print will need but I do like the color blue.



The only thing that is missing is- what it looks like ? But I don't think it’s supposed to look like anything.

Explain How would a 3d printer fix this
My solution helps solve my problem by limiting the amount of toothpaste that comes out of the tube, help me not make a mess with the toothpaste, and make my mornings faster.
