I am not sure what brands are using this concept of lids for one gallon paint cans. My go-to brand is Behr and I have recently bought several gallons of what my Granddaughter has labeled Princess Pink and Prince Purple. Print time on this is about 2 hours and 55 minutes. I am using ABS with 30% infilling for strength. It is designed for a 3/8” ratchet. And it works a lot better than channel pliers when using the smaller, 2 ½” brushes or smaller. I was working with small Easter items and did not need a wide brush. The design work was done in Fusion 360.
It is item 5274128 on Thingiverse.com.
Thanks,
Rex
