Um2+ hotend spring replacement piece? Where to buy?

[axislab 8]

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?

I think my version is better for a few reasons - but mainly because it has a hole so you can see what's going on inside.

Bah, Brilliant.

I didn't even think to look for printed mods. Or of printing one for that matter.

Yes, this should do the trick.

Thanks yet again.
