Filament holder with bearings that uses the original bracket on Ender 3.
You will need a 16 cm long M8 threadbar.
2 pcs 608Z bearings.
2 pcs M8 nylon lock nuts.
And 2 M8 washers.
For the "Optional_thread_guide.stl" you will need some glue.
I use Loctite Super Glue Precision.
Assembly the whole thing except for the thread guide. As the last step glue it in place. Make sure to leave some room between the thread guide and the filament holder.
Put a pice of paper or somethong between the parts when you glue it in place.
If you like this model, please post your make!
But if you love this model, buy me a coffee ;)
Soon 100,000 downloads and only a few who bought me a coffee, you cheap bastards ;)
It doesn't directly encourage me to post more of my models...

New Version available Here - https://www.thingiverse.com/thing:3343456
Designed a Vent Ring that also directs some of the wasted Wind from Hot-End's fan.
Wanted a full Circle that was Unique,
Forced air in certain areas for faster print speeds,
Would not send anything towards the Nozzle,
Redirected the Hot-End airflow that goes low.
This is the Surviving design.
You may need to Loosen the screws of your hot end fan housing to level this out.
many come from factory just slapped together and not adjusted. It's a $200 printer with
great parts. Please don't over-tighten this into your fan.
The original version that works best on early Ender-3's.
Short is  for more clearance from bed
I have thinned the screw mounts on short 2 for the newer Ender-3's that have short screws
.stp file of Short Version has been included
For those who have tipped me a coffee, I offer back a huge thanks.
For those who wish to, I drink the cheap stuff.

Hey there!
First off all let me tell you that I'm starting an youtube channel where you can learn Matlab. Matlab is a very powerful engineering tool widely used in the present day. Please, if you like this part it would be very helpfull if you subscribed to my channel!
Thank you!

Part information bellow,
NEW VERSION:
As many users have requested requested, the tip is now inclined so the air blows directly bellow de nozzle;
A full sleeve has been added to minimize the airflow loss beetween this part and the blower;
Better dimentions;
I've included the gcode I used on my CR-10 to print this part (for PLA only) in the file section as well as the STL of the new version.
This is an easy to mount cooling mod for the Creality CR-10, the other CR series and the Ender 3.
This mod redirects the fan air flow directly to the tip of the nozzle without being too big or obstructive. If you are looking for the best print quality this is definitely a must for your Creality…
