I just got my first flawless 3d print. I started with abs, in hindsight maybe not the best idea but wanted to be able tu utilize the properties of abs.
Now I want to start conquering pla. Since abs and pla kinda need the opposite regarding thermal environment I have to put my enclosure by side and start thinking about cooling fans.
I found some verry different design for cooling fan mounts and im not sure which to use.
Can you guys recommend any design in particular?
I found this minimalistic one: mobdro kodi.
And some more elaborate ones that seem to funnel the air. Happy for your suggestions

Also one tutorial I saw the guy hijacked the electricity from the extruder fan. That way he can regulate the speed only in pairs.
Do I need to change something in the firmware?
Any other suggestions for some1 new to pla.
Kind regards and thanks.
