YABA is an abbreviation for "Yet Another Blower Adapter"
This is an update or a revised creation based on some of my previous adapters. It's a swap in mod for the stock 40mm cooling fans on printers like the wanhao duplicator i3s. This takes a 50X50X15 blower fan. These fans are common place when it comes to being used for part coolers on these printers. Browse the pictures to see how it installs, the hardware, and how it looks on the actual printer when homed.

Treat infill and resolution as you would for most functional based works. You do need support for this model. I provided a picture of the support I used and the position in which I printed this part as well. That should give you a good idea on how to layout the part for supports.
This mod does require some hardware, this includes a fan along with a screw and nut to firmly attach the fan onto the part. I made this mod use the stock screws that firmly attach the stock fan to the heat-sink. You can find a wide variety of 5015 fans on various online shopping sites, however you should always check to see if you are running 12 or 24 volts.

Like I said in the summery this is based off of some of the previous work I did. You can see that the YABA is tagged as a remix of that work. I would just like to point out some of the differences I made to this VS the previous work.
I worked hard to remove material from the model while still allowing it to be easily printable. This included switching to a one screw holding system, cutting corners literally, and cutting out a few sides with stuff like the parts name and a creator mark. I tried to place the creator mark and the part name in areas not so often viewed.
I reshaped the extension that holds the fan to the part so that it avoids covering the air intake of the fan. This also allowed me to slightly increase or bulk up the thickness of the extension to make it stiffer.
I did not change much on the fan opening other than removing the cutout I had on the previous work. When I created the new arm extension I moved the fan placement. The fan was not actually using the cutout meaning that it was acting as a small exhaust point. This should mean a better fit with less chance of the air exiting through the intake.
This is a simple list and short description area of the files included on this part.
YABA_spacers.stl: This is a spacer to be used with only the YABA_without_spacers.stl file if you have lost or don't have the stock spacers for the machine
YABA_without_spacers.stl: This is a version of the YABA that does not have built in spacers. This will allow you to use stock or other spacers.
YABA_with_built_in_spacers.stl: This is a version of the YABA that has built in spacers. These spacers are the same length as the YABA_spacers.stl file.
diverter_without_spacers.stl: This was designed to help divert air to exit the back of the heat-sink. Was made to work with the version of the YABA that does have built in spacers.
diverter_with_spacers.stl: This was designed to help divert air to exit the back of the heat-sink. Was made to work with the version of the YABA that does not have built in spacers.
YABA with diverter and spacers.stl: A version of the YABA that has the spacers and diverter built in. An all in one print.
YABA with diverter no spacers.stl: A version of the YABA that has only the diverter built in.
A Section where I can post updates and leave the summary alone.
4/22/17: Added new stl files to this page. The files are the (Digikey fan YABA with diverter and spacers) and (Digikey fan YABA with diverter). These files were made to fit a specific fan. The fan can be found on the digikey website. I am not being paid or sponsored in anyway by digikey. I simply had someone recommend me this fan from their website. It would not fit the opening of the YABA so a specialized set of versions had to be made. You can follow the link above to the digikey fan I used. It's just a normal link to the fan.
9/5/2017: It's been a while, but I have not forgotten about the YABA. I have added two new files of the YABA with built in heat-sink diverters. The idea being that they will help divert air to exit the back side of the heat-sink. As the norm I have included one with spacers and one without spacers. I added pictures of a print of the file without spacers built in.
7/31/2017: Decided to just try and allow the air out one side rather than trying to force the air up and out. It just moves through the cutout instead. Hoping at-least with this more airflow will get out and the air escaping from the front is almost completely gone. Going to keep testing with it though.
7/29/2017: Updated the diverter with larger openings, this should hopfully allow more air to escape through the top half naturally, the air hear the bottom will most likely filter into the heat-sink hole.
7/28/2017: Placing the page into work in progress as I work on these diverters. Added a new heat-sink diverter for both versions of the YABA. This has not been long term tested as I came up with only a few hours ago. The main thing it does is force most of the air flow further into the extruder assembly and out of the top via the two holes in place for that specific purpose. What could this accomplish? It's currently unclear as I have not had long term testing behind it. The thought is that it may possibly affect the filament feeding, and stepper motor temperatures in a positive manor. Along with hopefully dispersing the air flow further above the X axis. These parts are thin and I printed them at 100% infill.
7/26/2017: Added a picture of the part with the built in spacers colored purple.
