PETG Ender 3 Vent Ring

After trying a LOT of various vent ducts, I have resorted to designing my own for the modern age. I say that because quite a few ducts I've found were actually designed for an older (post-2019) version of the Ender 3 with slightly different clearances around the extruder and vent opening. This vent is as close as I could to taking up as little space under the extruder, giving plenty of space to avoid rubbing the ongoing print for a long while, provided it is made of PETG.

It also has a solution to something I've struggled with in other ducts: interior supports. It not only has lines across the inside to guide airflow, but it also has simple chamfer transitions to support the bridging layers and prevent them from sagging (especially with PETG) and obstructing airflow.

This is one of the first times I've published something to here, so please give me feedback on this vent, I want it to do it's job well!
