Most useful for those who have transitioned to the Olsson block or regularly change nozzles.

I wanted ducts that were compact, allow for easy access to the hot end, and allow for some cooling when required. I don't regularly run my fans so extreme cooling is not a priority for me, although I'm sure these ducts should be more than adequate for most hobbyists.

I've included single files and a print all in one STL. The only hardware you should have to source are 4 M3x8mm screws. The hanging points have been thickened for added support and avoid cracking as most printed fan ducts do. For the mounting of my fans I only used 2 screws and that's more than enough to keep them firmly in place.

This design is currently a Work In Progress.

nice design. can you modify for the fans to snap instead of screw-on?

and also can you kindly advise the fan speed? eg 50% ?

I like you desing very much. The only problem I get when mounting the fans is, that the thing cracks because of the holes are too small. First I thought it's because I used PLA90 but it also happens with normal PLA.
