Spout Plug

I found out the Gallon can spout by Richy_T will fit my quart cans for bestine thinner, but I don't want to go through the hassle of taking off the spout every time I portion into my working jars (sometimes multiple times in one work session). This is designed in Tinkercad and made to be printed in TPU or another flexible material. It's just a cap to cover the spout to prevent the thinner from evaporating quickly.
