A square pencil case was made. The dimensions of the box are 90x90x100mm. On the outside of this box, a regular pattern is made of rectangular segments that create a tentative X grid on each side of the cup, which is identical on all four sides. 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.
