CalorieMate is a brand of nutritional energy bar (from Wikipedia) in Japan. I like Potato version, but it was discontinued...
This case is for a half size package.
No support needed.
Printer: AFINIA H480
Settings: Layer thickness 0.2mm, without support.
Added "minimal" version (must remove paper box), and modified door's "barbs" height 0.4mm -> 0.6mm.
