!!!You should prepare/remix a hotend holder before printing this!!! (I may provide a update, but I don't test it)

Larger size, keep the style of Satsana fan duct.

I design it for fitting E3d v6 and the adapter (https://www.taobao.com/list/item/wap/649967657270.htm) for my Ender 3 Pro.

Large hotend is possible.

Easy print with less support. ( It is possible to add support to the largest hole only. )

Add 5% or more line width is recommended. (I use 0.42mm line width for 0.2mm layer height)

Fixed the incorrent screw hole positions by cutting larger holes.
