Full-colour FFF? Continuous fiber? Embedded copper 3D printed circuits? Hollow extrusion for light parts?

I've now modelled the cooling ducts. The airways themselves are not optimised at all, but it should serve as a good starting point. 

I also did this to see if there was anything else I might need before I bought the AliExpress BOM, since I've found it unrecommendable to buy components before the assembly file has been completely modelled.

I'm planning to self-tap M5 screws into the 6028 fans. Here's what it looks like with the fans inside:

Hopefully, the plastic being 3mm away from the hotend is good enough for it to not melt.
