What is this spring and needle in the parts box?

I found this spring attached to a needle in the parts box. What’s it for?

I’ve looked through the spare parts list (and for the other store regions too) but don’t see it anywhere.

For reaming out a 0.4mm nozzle without removing it from the printer. If you get a partial clog.

Or at least, that’s what I’ve used mine for. :slight_smile:

I believe it is designed to help you poke out any blockages you might experience in the hot-end nozzle.

I always thought it was too thin to do a good job and that it might break.

It’s an acupuncture needle.

It’s for relieving stress when you first layer just won’t stick to the build plate. :wink:

just used it yesterday. But could not get in to the nozzle. In the end i used the good old cold pull method.

Ah, I see. Thanks for the replies.

Shame it doesn’t work for that purpose.
