There are different results when it comes to the default duct. In case there's need for that one can try to use the Low / Wide variant of the duct, it's further from the heat block and closer to the bed.

STEP files? CAD Link?

If you are looking for the CAD link to tamper with the design or to export the parts in formats other than STL you can find the links bellow.
Be warned though! The link directs to a live - bleeding edge - version of this particular EVA module - there is no promise it will be the same version as what you see above nor does it have to be the version Rat Rig provides.

I understand, please give me the link
