A round pencil case was made. The diameter of the base of this box is 90mm, and its height is 100mm. On the outer sides of this box, a template is made, which consists of simulations of coin halves, which are arranged according to certain templates both along the perimeter and in height. 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.
