Jan 2020: It may be worth checking out my latest design - Hydra Fan Duct & Tool Change System which IMHO is far better in a lot of ways than this Hero Me remix. Link: https://www.thingiverse.com/thing:4062242

091219 Please Note: Creality seem to have changed the design of the 4010 fan and the size of fixing. Therefore until I have had chance to revise the 4010 duct may not fit with newer machines or replacement fans..

Uploaded a WIP fixing plate for a EZABL sensor. This was a member request with a 18mm mounting hole specified. Never used one so this is definitely work in progress. All comments welcome

Uploaded 5015 Ducts (Straight & Offset) with BL Touch mounting panel and mounting plate. I do not own a BL Touch so this design was based on 3D models so definitely WIP. I have increased the thickness of the Duct mount to the base unit to make it even more robust on the LH duct. You may now need to use M3 x 10 mm to fix to the base unit. You will require 2 x M3 x 6 mm bolts to mount the BLT fixing plate to the duct and 2 x M3 x 6 mm bolts to mount the BLT to the fixing plate. The fixing plate allows for 6 mm height variation.

Uploaded 5015 Ducts V2_4 RH & LH. Improved the seat to create a much firmer seatfit.Revised the duct vanes to provide more directional air flow over nozzle.

This is my second remix of kelokeras & Mediamans Hero Me Fan Duct. This remix involves the base unit, Dual 4010 fan duct and the dual 5015 fan duct.
Update: Below: I do not use any form of levelling sensor so at this time I have not considered these options.

ratherbe_flyin has made a bracket for the BLTouch mount which he tells me works perfectly at the following link:

The parts still use the original locking part but the Base units will only be compatible with the duct parts in this thing.

The parts in this thing are based on the standard stock hot end only at this time.

All parts were rebuilt from scratch in Fusion 360.

Apologies in advance if any of the items below are included in another remix I have not spotted

In this remix I have:

1.Created a 2 point fix solution with only one tab to provide a robust fixing solution that does not rely on very tight tolerances to create rigidity and over strain parts.The parts facilitate a standard M3 Pan Head x 10 mm bolt without any trimming with scalpels or knifes.

2.Extended the wire management of the fans, hiding all cables, with a cable channel & cap across the hot end fan and a restraining clip to the main cable feeds.

3.All parts included can be printed without supports ( I have integrated a break away foot to the 5015 duct RH & LH ducts to retain stability when printing).

4.Two part fan duct solution removes retaining cross bar, increases nozzle visibility and slightly reduces weight.

Printing and Installation Notes

1.Please refer to the original thing for basic installation guidance, if unsure please contact and I will attempt to explain any specific installation issues. I will upload a exploded view of parts later.

2.Please be careful when manipulating fan duct wires. Most lost cost fans have very delicate soldering and can easily break. I have re soldered many wires during the prototyping of this thing. I have found the Creality branded fans to be much more robust and better performance than other unbranded items.

FYI I have purchased these which appear genuine and low cost if you can allow the delivery time. Link:https://www.amazon.co.uk/gp/product/B07MBCM645/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

3.The Dual 5015 installation at best can be described has finicky. You will need to clip the WM cap into the base unit with the Left Hand fan cables in place before insertingfixing the Left Hand Fan. After inserting the Left Hand Fan you can then draw the excess cable through the WM Cap. Make sure that the soldered fan connections are not strained.

4.I have included a basic 1.5 mm pilot hole to retain the 4010 fans with the stock M2 bolts that are used with the original assembly. I have found that the 4010 fans are a snug fit and I have not used the original bolts at all. It may be best if wanting to use the stock bolts to thread the holes prior to assembly with the bolts.

5.With the Ender 5 base installation I found that just using the top rear fixing bolt was sufficient in addition to the lock plate. If you wish to use the lower rear fix as well, use a M10 x 6 mm bolt, the lower hole is shorter so not to conflict with the duct fixing holes.If you have any problems with this please contact..

6.I have noticed that the LH duct can conflict with Ender 3 Heat Bed cable retention housing at the extreme rear left. This must be something inherent with the original thing because the duct footprint as only changed slightly. Just be aware of this if printing anything which is placed to the very rear left hand corner.
