Summary

This is not my design! This is a remix of the V-Ring for the ender 3. The original was hitting prints from time to time since it is so close to the nozzle end. I just quick and dirty shortened the vent by 1.2mm to give it a bit more clearance from the prints. Works fine for me and seems to handle the heat up by the hotend well (i have a rubber hood an my hotend).

btw still prints without supports
