This is a crown/bob add-on for the Bullseye Duct: https://www.thingiverse.com/thing:2759439Note: I have only designed this for the Ender 3 Pro version of the Bullseye. It will likely need to be remixed for use on other printers' versions.Purpose:Enables disengagement of the Bowden connector more easily (Press on the big disk).Tilts/rotates with the Bowden tube during the printing process to relieve stress.Acts as a top cover for the Bullseye versus dust, etc.
