Uploaded a fan design that seems to be working. It's a bit of a tight squeeze but it seems to work. Only issue I have with it so far is that if the fan turns on to max with a large flat print, it will cause heater issues, so just turn down the fan settings.
Just an update. Don't mind the wires. Currently switching to a DuetWifi control board with 24V so I won't be able to test much in the process. Fan duct is printed but needs some tweaking. It blows a lot of air but is aimed a bit to high and is to far away from the tip.
This is a design in progress. This is meant to hold the E3D Cyclops. It's still testing. It can be used as the base for the Chimera as well tho it will need a custom fan. I'm currently working on this still. Will be creating a fan for it as well. Currently using the Anet A8 Fan Duct Spaceship edition and it's working fine.
It's not exactly centered because I don't have it installed properly but I will get there.
