A circular pencil case was created. The container features an upper and lower diameter of 90mm and a height of 100mm. A regular pattern of hexagonal holes is incorporated on the outer surfaces of this container, extending across the entire circumference of the pencil case. There are 8 hexagonal holes along the height dimension and 26 along the circumference. The edges have been rounded to prevent users from getting injured or cut by sharp edges. The model was developed in SolidWorks and exported as an STL file. This pencil case is intended to be printed using a Bambu Lab P1S 3D printer equipped with a 0.4mm nozzle.
