Ultimaker 3 extended nozzle cover part broke off. Need help fixing it.


Hello so my UM3 extended was printing just fine until the nozzle cover broke off and the plastic or rubber bit on the inside that holds nozzles split in two. I have gotten the cover back on but the nozzles have been having trouble with getting stuck or not retracting properly due to thDisplaying IMG_9358.JPGe damaged cover.


Is there any way I can fix this? Or get replacement parts?  Thank you for your time

Hi, in general the printer works also without this cover.

If you buy the maintenance kit, there are 5 spares:



you can also get only the silicone parts pretty cheap:

I haven’t found any kind of technical spare parts list. I usually keep the UM3 maintenance kit and the belt set in stock, to make sure to fix small issues just in time.

You could get the measurements by just measuring your printer ;)


On you concern with the tape: I’m printing since more than a year with one of my printers (UM3E) without the silicone cover. I’m only printing stuff that doesn’t need special bridging abilities or very high precision. So I don’t really care about the the airflow not being perfectly.

I haven’t made any other bad experiences with the lack ob the cover - but no guarantee ;)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
