Kobra X Nozzle Change
I've seen too many posts of broken clips from brute force and lack of a good clean guide. So here's my contribution back.
Kobra X Nozzle Replacement Guide
How to replace the nozzle without breaking the retaining clip
Important: Do not force the retaining clips. If a clip requires significant force, stop and check the nozzle position.
1. Seat the nozzle
Firmly seat the nozzle into the heatsink. It should lay flat against the smooth edge, and the ribs should be fully inserted.
2. Partially close the upper heatsink latch
Close the upper heatsink latch about 3/4 of the way, not completely. The notch from the clip should fit into the groove.
3. Close the upper retaining clip
Close the retaining clip. It should close smoothly and secure the heatsink around the nozzle. If you have to force it, stop. The nozzle is not fully inserted.
4. Close the small lower-right latch
Close the small latch on the lower-right side.
5. Close the larger lower-left latch
Close the larger latch on the lower-left side after the right latch is secured. Both lower clips should now be fully closed.
6. Secure the silicone sock
Fit the silicone sock over the nozzle assembly. Make sure the sock is fully seated, then check the retaining notch on both the left and right sides. The sock helps retain heat around the hotend.
Done.
