Cetus Duct

thingiverse

I reviewed the original design and regret that the original print quality was subpar from the start. Upon initial inspection, I felt it fell short. The original duct proved to be faulty due to repeated attachment and detachment, which led me to recreate it from scratch since no print data was available. My goal is to minimize unnecessary space and refine any errors during the redesign process. The stop hole processing in the original design appeared unusual, as did the formation of air channels for the extruders. I couldn't imagine such a design coming from experts. Version 2 featured a revised duct with clear filament injection visibility, making it easier to work with. Version 3 further improved filament injection visibility, making it even more challenging – but I loved this one. The ejection of filaments became easily visible as well. It would be beneficial to remove the steel plate in front for enhanced visibility during filament injection. The original Cetus design allowed easy visibility of the injection process, whereas the MK2 design has become increasingly complex. v4.00: I decided against cooling the tip of the injection nozzle, deeming it unnecessary. Perhaps, a slight effect could be achieved with a 0.2 mm nozzle. This would reduce clogging due to priority injection. v4.01: Given that zero cooling resulted in difficult raft peeling, I slightly cooled parts other than the injection nozzle. v4.02: Experimental version. v4.03: Usable version. The version 4 series is easy to use because it's simple and easy to replace. It can be used properly depending on cooling or injection priority. This modification is recommended due to expected insufficient cooling and poor filament delivery. https://www.thingiverse.com/thing:3692742 v4.04: Safe design, recommended for everyone. v4.05: I found it difficult to install, so I provided a guide. v4.06: Increased airflow around the injection nozzle, decreased airflow around the extruder. v4.07: Decreased airflow around the injection nozzle, increased airflow around the extruder. v4.08: Balanced airflow around both the injection nozzle and the extruder. Today, I created various ducts, hoping to help you decide which one suits your needs best. My criteria for selection are the surface after peeling the raft and the surface left behind. The condition of the raft after removal is particularly crucial – you can judge by touch. The effort of raft removal has been minimized, but there should be no issues with shaping.
