Paint This!
thingiverse
This snaps into place over a paint can opener. Buy a paint can opener from the dollar store and there you have it. Bottle opener, paint lid scraper, paint roller scraper... This works on all metal gallon jugs of paint, the plastic jugs dont have the same rim geometry, but still works ok, it fits into the slot to clean up what is left in the grooves... Two files are here since this is to be used with paint and possibly other chemicals like acetone or paint thinner I recommend printing these with PETG as it will be strong and chemical resistance and yet responsible, I added the recycle sign for PETG... Enjoy. https://youtu.be/Ncqse_WQPQ0
