UM3 (E) Where to buy the O-ring for the Print Cores?

[jschwar 3]

I am looking to purchase replacement O-rings for the print cores. The little red ones that make a seal with the silicon nozzle cover. I used to find them on fbrc8, but not finding them now...

Hi jschwar,

the O-rings have been withdrawn by Ultimaker some time ago.

For the UM3 they still can be used, but there's no need to, the silicon cover alone makes a sufficient seal.

So just use the print cores without the O-Rings.

Great, thanks for the insight!
