Auxiliary Cooler (3x40mm) for Ender 5 / Sovol SV-05

So I finally got to a point where I'm hitting a really hard to crack cooling issue on my Sovol SV-05. Even with a 5015 and a directed duct, I cannot get sufficient air on PLA for 300mm/s printing.

Inspired by the auxiliary coolers of the Neptune 4, the P1x and the K1, this is what I came up with.

Its supposed to be used with heatset M3 inserts and 40x40 fans.

THIS IS CURRENTLY UNTESTED (prints fine, just need to come up with a wiring solution now).
