This is a dual blower fan duct for E3D V6 Hotend / J-Head hotend. This duct is a 2-part press-fit, so no screws or glue needed (glue optional if desired). The press fittings are angled so they should fit with even relatively poor tolerances. I have also included a single fan version for those who don't have 2, or find 2 to be too much cooling.
I have also included the original Blender file for easier remixing or tweaking.
Do not print with PLA. It is too close to the hot end and will warp. Mine is currently printed in PETG and I have been very happy with it so far.
