Justrite Plunger Can - Anti-Evaporation Lid & Seal

As a knifemaker I use a lot of Acetone for cleaning parts. I have had this old Justrite 2 quart plunger can for years and always hav eused it. One of the issues I faced was the evaporation of the acetone when not in use. Now, normally I would just cover it with something but now that we have a 3D print option, why not make a dedicated lid?

This lid has a TPU insert to act as a seal against the evaporation. I have been using it for a couple of weeks now and it does make a huge difference.
