A circular pencil case was made. The box has a diameter of 90mm and a height of 100mm. On the outer sides of this box, a regular pattern is made, composed of smaller rectangular segments, which look like windows on a building, inside a larger rectangular segment, which extends around the entire circumference of the glass itself. The smaller windows make a 5x6 matrix, and there are only 3 large rectangular elements in the perimeter. The edges are rounded so that the user does not get hurt or cut on sharp edges. The model was made in SolidWorks and exported as an STL file. This box is intended to be made on a Bambu Lab P1S 3D printer with a 0.4mm nozzle.
