I was making bread and needed 3 tablespoons of butter. Since just part of a cube was in a butter dish, I had to guess how much to cut.

This thing divides a standard, 4 ounce cube into 1 Tablespoon segments, just like the wrapper you threw away did.

0.3mm Z, medium speed, 17 minutes, 7 grams ABS, with a raft.

If you want to keep it clean, cover the butter with a bit of plastic wrap, and mark through it.

Metric file included.
