A square pencil case was made. The dimensions of the box are 90x90x100mm. On the outer sides of this box, a regular pattern was made, composed of tapered triangular prisms tapered by half the length of the base, which is identical on all four sides. The edges are not rounded, because the template looks better in the original, than with folded 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.
