When your radiator has too much air in it at the start of a new season, the plumber will use a key like this on the bleed valve to allow excess air to escape out of the heating system.
This plastic key should be wrapped in thread or wire for long term duty. PC blend or ABS are recommended.
Print at 100% infill with 4 perimeters. Turn on supports and choose snug supports. These snap off easily.
