Silocone Nozzle Covers Don't appear to fit.

Recommended Posts

Posted · Silocone Nozzle Covers Don't appear to fit.

My silocone nozzle covers have started to come apart so I've ordered more, and am now trying to install them.  I have an Ultimaker 3 Extended.   But the metal bracket that the silocone is to be installed in on my device differs from the one in the pictures.


Mine has two "Rounded Ice cream cone" shaped holes, whereas the shape in the pictures, and the shape of my new silicone nozzle covers... is just a pair of squares.  The new ones are a fairly different shape, compared to the new ones I bought.  The old ones had "wings" on the side and a "slot protrustion" in the center.  The new ones, dont have either of those.  So perhaps I bought the wrong one?  But it looks right from the images online.


Note... The whole extruder/fan assembly I have currently is not the original.  The original failed catstrophically, and I have a replacement.  I assumed it's the exact same one, and has been working fine... but perhaps I have one that differs from the OG assembly.


Any recommends for me to resolve this?  Get different silicone nozzle covers?  Replace the metal brackets that they attach to?  Where would I find the appropriate Mix n Match part that gets this done?

    @undertone_dj - email support@fbrc8.com.  Send them the serial number of your printer in the email (sometimes they won't answer questions without it so this can save some time).  Tell them you changed the print head so that your printer may have changed versions or something.  Show a photo of the old and new silicone part.


    background: fbrc8.com assembles all Ultimaker printers sold in USA so they probably built your printer.


    I think Ultimaker may have modified the part to work better but it's possible you got the wrong one,  I think if you google on their site you can find photos of how to change the rubber part.  But this part exists for UM3 and S3 and S5 and the S5 one definitely is incompatible with UM3.  Not sure about S3 but suspect it is the same as S5.

    there's been a change some time ago.

    Below is a picture which compares the "original"/old style covers for original UM3 printheads and the new ones for the revision.
