The problem that I want to solve is to make the door stop closing and stay open when it is needed by making a door holder. It looks like a stretched triangle, it has a tall side at the top and it decreases its shape going down. This problem affects some people that want to have their room open, but it keeps closing. The problem is located at the bottom of the door. Fixing it is important, because you might need a door holder when you are bringing boxes or something that you have on your hands and can not open the door, and the door holder would help to keep the door open. It is something that a 3D printed part will fix. The color that I would like to use is black.

My solution will help to keep my door open when needed.

The size of the solution is small, the shape is a stretched triangle.

The measurements of the solution are, length 170.00mm, with 40.00mm, height 45.00mm, inside
