About this 3D model

Hello! So where do I begin, I own a Qidi X Smart 3 and I believe the hotend is very lack lustre for how good the printer itself is. I currently get 15mm3/s flow on the stock hotend, I want to increase this, now there are a 3 options (I will provide links to everything) first theres a Qidi CHT Nozzle, then theres a v6 adaptor and you can combine that with a CHT V6. These 2 will give a little bit more flow but the best combination I believe is this meltzone extender I found on aliexpress. I have ordered all 3 so I will do tests on them when they arrive to see which combination is the best however the melt zone extender requires a longer duct compared to the other 2, so I designed this duct. I cant for the life of me find the original design I used to make this duct sadly, so I am very sorry if this is your duct. I forgot to mention this duct requires the use of a normal 5015 Blower fan not the weird wide mouthed one QIDI use. ALSO! I forgot to mention you'll need to get a spacer or something to lower the inductive probe, I am currently working on one and will have it uploaded asap! If you have any questions you can either comment them or join my discord: https://discord.gg/khrPzqgE5M I am also may be working on another upgrade for my X Smart 3 but I will see if that is possible.
