Um2+ hotend spring replacement piece? Where to buy?

Recommended Posts

Sorry for the wording in the title, I'm not exactly sure what to call the part that they have replaced the spring with. Sleeve maybe?

My olsen block conversion is getting the best of me, within minutes the hotend seems to have enough pressure inside to push the insulator right up and compress the spring. As seen in the first pic. Causing jams of course.

I see the new machines get rid of the spring altogether, with a metal 'sleeve' piece. (Second pic)

Is there anywhere I can find this part separately?
