Fenrir progress update

Fenrir is my open-source, enclosed CoreXY 3D printer; this February 2023 update explains splitting the parts into smaller pieces for easier ABS, ASA and PC printing on a Prusa MK3-sized bed, which also let the printer grow by a few centimetres.

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.

Hi everyone! 

I wanted to take a moment to apologize for the lack of updates in recent times. I have been working diligently behind the scenes, testing and modifying the various components of the Fenrir project.

As you may have noticed from the image above, I have decided to split the Fenrir parts into smaller, more manageable pieces. The reason for this is to make the printing process much easier for all of you. Printing large parts can be a challenge, especially when using ABS, ASA, or PC. By breaking the parts down into smaller pieces, I have been able to resolve this issue and make the printing process smoother for everyone.

Additionally, by splitting the parts, I have been able to increase the size of the printer by a few centimeters. This was needed because I had set strict constraints for myself, with the goal of ensuring that the parts would be printable on a Prusa MK3 or larger. Now, with the changes I have made, this is no longer a concern.

Thank you for your understanding and patience. I look forward to providing you with more updates soon.
