This is a CORE One L mod for cat lovers: the Nextruder level gets a cat paw that is trying to catch the bird on the grille handle every time the printer opens or closes the chamber ventilation.
Printing
There are two versions (of the bird):
- The C1L version can be printer on the CORE One L, or any other printer, with a manual color change, and has a very tiny bird on the bottom of the grille handle.
- The XL version can be printed on the XL printer or with an MMU and has a bigger bird on the side.
Because the part belong inside the chamber, which can get as hot as 60°C, I highly recommend not using PLA. I printed them from PETG Carbon Fiber and PETG Prusa Orange.
Installation
The Nextruder lever is attached by one screw on the back side of the Nextruder. You can remove it using a 2.5mm Allen key.

The grille handle is also attached by only one screw. You can remove this one using the T10 screwdriver.

Both are doable without disassembling the printer, but it's easier if you can see inside.
