Summary

This is a one-to-four tablespoon measure. Each level is an additional Tablespoon.
It is accurate. One tablespoon equals 0.9 cubic inches ( 0.9023438) and I took pains to be within a couple % of that.
I own a few measuring spoon sets, and was surprised to see some of the tablespoons are much larger than others. User beware.

2 T = 1/8 Cup.
4 T = 1/4 Cup.

Wall thickness is ~2mm. , 0.08".

1 hour, 25g ABS on an Afinia H479, default settings.

All prints are porous. Small holes, cavities and internal spaces can harbor food residues, and provide a home for bacteria. It's virtually impossible to sanitize a print without destroying it. So I recommend prints be used for dry goods only.. like salt sugar flour instant coffee and so forth.

There are ways to completely fill and seal the body of a print, but it is a chore. I've used a liquid paraffin wax bath, under a high vacuum. The air is withdrawn and wax fills all the spaces. Some companies use an epoxy instead of wax, but that's far more difficult and expensive. Wax melts at low temp, so one would gently wash in cold water only.
