I was in need of something cheap that could filter the IPA I use to clean my resin prints so that I could continue using it. I couldn't find anything so I made this funnel that you place one or more coffee filters into and it will remove all of the micro bits of resin from the IPA. Some brands of filters clogged very easily so be careful if you're using it for this reason.

It will require supports for the handle/hanger. However, you should make sure it doesn't print supports by the spout as that will print fine without them.
