keg level indicator

Hole is sized for a 6mm x 3mm neodymium magnet. It's a snug fit to make sure the magnet doesn't fall out.The flange on the float must point down to ensure the external indicator remains accurate.The indicator will probably fall off when the keg is nearly empty. This is a very simple print, with no supports and 0.2mm resolution. PLA seems to work fine, though ABS would probably be more durable.
