Ultimaker Silicone Nozzle Cover (UM3 & UM3 Ext)

The silicone nozzle cover on the Ultimaker 3 and Ultimaker 3 Extended fits on the underside of the printhead to help keep the temperature stable and prevent the back-flow of filament.

Note: Sold individually. There are two versions of the nozzle cover/nozzle seal and metal bracket for the Ultimaker 3 family of printers. These nozzle covers will fit the version with two square-shaped holes in the openings at the bottom of your printhead.
