Ender 3 Vent Ring with offset and spacers

thingiverse

Ender 3 vent ring 2 upgraded with extra features. A spacer was added in the z-axis direction to maintain ring alignment from the bottom of the extruder housing. This results in the ring staying level with the print area, even when screws are over-tightened. Moreover, additional spacers were included behind the screws to prevent over-tightening and provide more support to the fan, thereby stopping plastic bending if screws become over-tightened. Initially, only spacers from the Ender 3 fan washer by Brassee were attempted, but they would spin when trying to screw in or out, hindering the screw's advancement. This issue was resolved by integrating them into the ring, making it impossible for them to spin. Screws are now much easier to insert compared to using spacers alone.
