Square pen cup with horizontal slits on the side edges

A square pencil case was made. The dimensions of the box are 90x90x100mm. On the outer sides of this box, a regular pattern made up of horizontal slits extending along the side edges was made. There are 8 of these slits along each side edge. All edges are rounded to protect the user from injury 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.
