shkoop // measuring scoop 1/3 cup and 1/4 cup

This measuring SHKOOP has an inner and outer marking at 1/4 cup, and is 1/3 cup at the brim. I figure it can be helpful for dry goods around the kitchen and other powders around the house.

Unless you're trying to make this watertight, you should be fine using 4-5 shells, 30% infill. I used PETG.
