Fenrir Update: Splitting the Largest Parts

Fenrir is my open-source, enclosed CoreXY 3D printer; this September 2022 update explains the decision to split the largest printed parts so they are easier to print, plus side projects such as BTT board cases and an Unraid server case.

Status (October 2026): Fenrir has changed a lot since this post. For the current design, parts and build status, see the Fenrir CoreXY 3D printer wiki.

Just a quick little post about the Fenrir CoreXY. I've been working on the design and printed more parts for it, and I've come to the decision to split the largest parts up a bit, to make them easier to print, so that's what I'm currently working on.

I'm also working on a couple of other projects, both smaller Patreon projects like electronics cases for some BTT boards for larger printers like CR10, S8+, and similar, A Unraid server case, etc. which you can see a preliminary render of below:

Fenrir updates and more!

More updates to come soon!

Thanks everyone! :)
