Pencil box

I created a pencil box for my grandson, who goes to the first grade.
The pencil box consists of 4 parts which have different color and are inserted one into another.
The upper part is threaded and twists easily. I glued the lower parts with superglue.
I drew his favorite characters from Minecraft and Lego. And also I signed one part with his name.
I added a 1 STL file with a picture without a name (part 3-1). You can change it.
Dimensions:
Case height - 195 mm
One-piece height - 50mm
Outside diameter - 55mm
I used ABS plastic and Fusion360. Each part was printed for about 3 hours.
