coffee portafilter dosing funnel magnetic 58mm

thingiverse

This is a portafilter funnel for a 58mm portafilter. Does not need supports, print with the magnet holes up. You will need 4 x 10mm x 5mm x 2mm neodymium magnets to complete this print. They fit into the little holes and keep the funnel happily attached to your basket while you use it. You may need to put a tiny bit of crazy glue to attach the magnets depending on their tolerances. On my version, all except one fit tight, and didn't need glue. Whereas one kept coming out. This version fits into a 58 mm portafilter, but the wall at the base where it enters the basket is 2.5mm thick all around, so the resulting internal space is 52mm or so. In using it for a while I have found that when distributing the grounds , my distribution tool never touches the walls of the portafilter basket in the top 3mm. It's not an issue really, but leaves room for improvement. Updated version can be found here: https://www.thingiverse.com/thing:5865473/files The inner diameter is 58mm+ all the way through on this new version.
