A twisted pencil case was made. It is formed from a square with a side length of 90 mm. Its height is 100mm. The box is obtained by rotating the square by height, in layers at certain heights. It is about a slightly larger angle of rotation around the longitudinal axis. Matrix arrangements of square holes are defined on the 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.
