Square pen cup with rectangular holes

A square pencil case was made. The dimensions of the box are 90x90x100mm. On the outer sides of this box, a regular pattern made of a matrix of 5x6 square holes is made, which is identical on all four sides. 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.
