Remix of @AlexB_524533's excellent Dual 4020 fan ducts for 4015 fans. I flipped the model 90 degrees in my slicer, cut off both scoops just next to the intake and scaled that down to 75% to take it from 20mm wide to 15mm wide. Carefully dragged the scoops back in place so they would align.

Note that for me, the screw holes of my 4015 fans were not the same as his 4020 fans, but I didn't know how to adjust them so I just solved the problem with zipties.

Would recommend printing in PETG with tree supports for the middle section. The overhang of the scoops are small enough to not need supports.

I managed to get clean supportless overhangs in an overhang test of 75 degrees along with a reduction in noise.

I used these 4015 fans: https://nl.aliexpress.com/item/1005006092917595.html, was planning on using them for the heatsink fan, but they're not PWM. So made the best out of a bad situation and repurposed them for parts cooling, worked perfectly.

Differences of the remix compared to the original

I flipped the model 90 degrees in my slicer, cut off both scoops in the Z-axis, just next to where the fans normally slide onto and scaled that down to 75% to take it from 20mm wide to 15mm wide. Left the rest of the air duct channel intact.
