Ender type Ring cooler-inator

A quick UNFITTED! test for a stock fan compatible cooler for ender 3. It will fit the 3d model though.

The petsfang bullseye is awesome, but really has one major flaw besides internal air resistance (multiple sharp turns) It does only fare ok on the backside of prints as the airflow seen is directed towards the back leaving that spot the least cooled.

So far this does print, gave the ring breakwaway custom supports as you cant have supports inside the ring structure, but the fan hole needs them.

This is very much work in process, but I ran out of filament .-.

For nozzles bigger than 0.4mm and any changes you want to make, you can edit the step files and make your own 1 line whide supports.
