This is a remix of my Manta Compact Cooling Fan System. This version is only compatible with the Ender 5. The Ender 3 version is here: https://www.thingiverse.com/thing:4943125
This Remix includes:
1.Reduced system parts list from 67 down to just under 30 parts.
2.There is now only one universal duct base for all variants including V1 & V2 versions, all fans, hot ends and tool head types. This will hopefully reduce user confusion when selecting relevant parts.
3.The parts have been optimised further for faster printing and stronger print orientation.
4.Includes two work in progress BL Touch mounting brackets. Although I own various levelling sensors yet rarely use them. Therefore the included brackets are a WIP starting position for others to develop for their own personal requirements. I have not tested either of these parts.
5.V6 style hot ends now mount from the front allowing easier maintenance and swap over and a much simpler Ender 5 base mount.
6.Bowden and Direct Drive assemblies can be swapped out without removing the Duct Base from the gantry mount.
7.Integrated, mechanically fixed fan shrouds for both the Stock & V6 style Hot Ends.
8.Improved the 4010 fan output via larger apertures which have reduced air restriction further..

Installation
1.I have uploaded an Installation guide and BOM. I have also included Fusion & step files for any bespoke tweaks or remixes.
2.If using 5015 ducts you may have to acquire a new timing belt similar to the MK1 version and use cable ties to retain the belt rather than the stock brass ferrules which will be in the way of the 5015 fan itself rather than the duct. You may be able to squeeze or bend the stock ferrule to accommodate this but I cannot guarantee this. I personally prefer using the ties has the belt tends to twist slightly less IMHO. A dual 401 fan set up will not probably need any change and should clear the stock ferrules (see uploaded images & Installation Guide).
3.I have used a slightly smaller Heat Sets\ Thermal Inserts in this thing because some of the remaining\retaining walls were quite small. Therefore I have included a 4.25 ID hole x 5mm deep for a 5mm OD x 5mm long M3 Heat Set.

5.Which fans ? I usually use a ball bearing based fan rather than a hydraulic fan, they tend to last longer.

Printing:
1.No parts require support. There are however, various integrated supports and sacrificial layers that will require cleaning off after printing (refer to the Installation Guide and the Part Preparation section).
2.All parts were printed with PETG, 30 to 40% infill with 3 perimeters.
