Ender 5 / CR10 users:
I don't own these printers and there are no accurate CAD models of them. Be sure to let people know in the comments what does and does not work. I know the original thing had a bracket specifically for the Ender 5.
This is compatible with the Heat Creeper by iAM_B3nFPS as I am using it.https://www.thingiverse.com/thing:4155280
F3Z File Included
Install Notes:
Install both Bases
Install both 40mm fan and hat loosely then tighten them
Install 5015 or 4010 fan ducts last and the screws should not bottom out just snug.

Hydra Fan Duct & Tool Change System for Ender 3 Ender 5 & CR10
See Below for Updates, V6 Edition Here: https://www.thingiverse.com/thing:4253359
Firstly many thanks to AlfaBarion for suggesting such an incredibly clever name for this thing.
This is a Multi Headed beast with ease of hot end access, adjustment and serviceability.
In this thing I have:
1.Designed a system with easy swap out of various types of tool\extruder head without having to replace the duct system (The short length of Bowden tube required may vary dependant on Extruder Head selected).
2.The Hot End can be fully accessed by just removing the front Heat Sink Fan.
3.Cooling Fan Duct height adjustment is front facing and therefore much easier to adjust and access. This also results in a smaller fan duct which can be assembled prior to insertion.
4.I have included multiple cable routes to aid overall wire management.
5.Robust Fan duct design with integrated ratchet system to provide a firm secure fixing detail with no duct vibration.

General Information
If you are using BoothyBoothy's great "Hydra Fan Duct" but suffer from heat creep when printing at really low layer heights for example, then look no further! The "Heat Creeper" is here to solve that for you and it won't blow you up, guaranteed!... ;)
It works great, if you converted to an all-metal hotend like me. If you are still using a PTFE guided hotend like the standard Creality one, then this part will probably not be needed as cooling performance should be sufficient.
Further Details
This part is designed to better channel the hotend cooling fan's air without introducing too much back pressure or resistance.
The cross-section is divided into four sub-sections to reduce the turbulence produced by axial fans, improving air flow over the hotend's heat sink. Also, the horizontal beam curves downwards to guide the air at an angle over the heat sink, further improving cooling performance. Additionally, the hotend is slightly embraced, so almost no air can move past the sides of the hotend.…
