Slick Ender 3/3-Pro/5/CR-10 2in1 duct 5015

Most compact hotend and part cooling system for Ender 3 / 3 Pro / 5 / CR-10 and other Creality compatible printers. Weights less than original metal housing, around 40 grams.

Designed to reduce unnecessary cooling of heatblock and printed part by 4010 heatsink fan.

It does not reduce the air flow generated by both fans as most of the designs do resulting in increased noise generated by attached fans.

Designed for 5015 24V blower and stock 4010 heatsink fan. It's a direct swap for stock metal housing.
