Anycubic Kobra S1 – Reinforced Rear Printhead Cover

After numerous attempts and iterations, I finally designed the ultimate, improved rear printhead cover for the Anycubic Kobra S1. Unfortunately, the stock factory housing has a structural flaw – the original latches are prone to stress concentrations and tend to snap easily if the mounting screws are tightened a bit too much. This design permanently solves that issue. 🛠 Key Changes & Improvements: The part replaces the original housing on a 1:1 scale and is fully compatible with the stock front cover – requiring no modifications. Reinforced Latches: The latch geometry has been completely redesigned and reinforced so they no longer snap or break, even if the mounting screws are overtightened. Extended Latch Teeth: The latch teeth have been slightly lengthened, allowing the front cover to snap on much more securely and stably than the original. ⚙ Recommended Print Settings: The piece shown in the photos was printed using standard PETG – this material provides the right amount of springiness and flexibility, allowing the part to flex correctly during installation.
