A circular pencil case was made. The diameter of the box is 90mm, and its height is 100mm. On the outside of this box, a pattern of all uppercase Cyrillic letters of the alphabet is made and 5 rows of them are shown. The edges of the letters are not rounded because the letters look better and print better with the original 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.
