I think at some point I will get all of the possible assorted sizes I foresee needing. Then, I'll make a bracket that'll have half-circle cutouts of appropriate size from left to right that'll mount to the wall. The funnels will be held at an angle narrow end down to facilitate draining (even though I clean them each time) but immediately below the spouts of the funnels will be a basic tray with a lip to catch any potential drips, and i suppose a guy could perhaps angle that into a little catch container.
