Padded case for storing and transporting eggs in a bear canister (I would still put it in a plastic bag though, just in case). Designed to be printed in vase / spiral mode (no top or or bottom) with a 0.25mm extrusion width. Printed in Sapphire and Aqua PETG from Atomic Filament.
btw, I like this brand* of ramen for backpacking, much more packable than the other kinds. It should be available in most of the Japanese markets (at least in California).
More backpacking designs can be found here.
