This cover stops the little bowden tube clip from falling inside of the print head, which can be a pain to retrieve.
When replacing the fan, thermocouple or heater cable, the heat shrink tubing that keeps the mesh sleeve from unraveling needs to be cut to let the connector fit through. This cover stops neatly holds the sleeve in place.
This part also fits if the heat shrink hasn't been cut.
Works with the UM2, UM2+ and UM2 Go.
