Hello my friends! (=

After a few months, I understood need to try another fans, instead 4010 model. So I bought radial fans, and I designed the new fan holder. What can I say... It's AWESOME! Super flow and without cooling of hotend.

If you using x carriage for Re-D-Bot, and you want use new fan holder with volcano, I recommend increase holes (bellow you can find image) or use updated version (Carriage_base_back.STL you can find there).

This fans is pretty powerful, and main printing going on 40-50% of fan power. If you want reduce noise of fans, in Marlin you can turn on sofware PWM for fans. You need uncomment this in Configuration.h

#define FAN_SOFT_PWM

P'S: In files I published "Fan_duct_filament_V2_nozzle_x2.STL" sources, so you can design your nozzles, with your own forms and sizes.

I used this fans.They are pretty good, I recommend (;

Supports is not required, but can help get better quality (;

About Assembly

For assembly you will need to print main fan holder (Fan_duct_filament_V2.STL) and two nozzles (Fan_duct_filament_V2_nozzle_x2.STL).

All screws (4), nuts (4) and washers(6) has M3 size. Two fans like this.

Sorry, forgot put nozzles in photo >_<

How I printed. Supports are not necessary, but helped get better quality. I like quality :P

Preparing screws with nuts

Mount the fans

Well done! (=

Now, connect nozzles and done.

In Finally, just unscrew old fan and replace by this.

Update Carriage_base_back.STL of Re-D-Bot x-carriage for Volcano (just recommended, not required). You can increase holes of your current printed element, but will be careful.

Could you modify this for the CR-10 2020 bar and with 5015 fans? Would be amazing, especially an option for just single left or right duct.

Hi ,
I printed your fan duct , But I can't understand hoe you fit hot end vent on it . Maybe I have to modify it because my hot end vent is posterior ) I have bltouch on the front)

Have you considered making a Titan extruder version? I love the design, it's very slick, but doesn't work with a direct drive setup. I'm especially keen on the use of blower fans, too many cooling ducts use axial fans, which don't work very well.

I like your design very much and would like to remix it for my Tronxy x3 (that hopefully will arrive soon :D).
Is it possible that you export your CAD files to one of this formats: DXF, SVG, STEP, IGES or IFC. This
software from SolidWorks is way too expensive for me.

Please explain, how can I open a file with a program that I don't own, because it is too expensive and Windows only?

Thank you for nothing.

Did you read? (=

Hey! Is it pla or abs? Absolutely unbelievable brinding!

Wow, thank you ((=
