Ender 3, 3 V2, 3 pro, 3 max, doble ventilador axial de 40 mm conducto de extremo caliente / colmillo. CR-10, accionamiento directo Micro Swiss y compatible con bowden. No necesita soporte para imprimir

Printed this wonderful thing with an installed Minimus Hotend cooler (also a VERY good solution - can be found here: https://cults3d.com/en/3d-model/tool/minimus-hotend-cooler-system) and overall support. What a mess! Don't ever try to print it with support! Almost impossible to get that stuff out of the fan ducts.

As Dom said on his design page, this baby prints flawlessly without any support - just put the top side onto the bed and go for it.

I instantly swapped the Minimus on my Ender 3 (with stock hotend) and it fit perfectly. Did a quick CaliCat to see, how the two fan ducts perform compared to one.

One word: awesome!

Now printing the v5 to check it out as well.
