UPDATE: 

++some Users had issues with the size of the 128 mm and 32mm axles therefore i upload 4 variants - small, medium, large, extra large.

please choose which one fits better for you, depends on the calibration of your Printer.

lots of Users hate me for that very Bad design, i am so SORRY for my really Bad design.  

-i am a beginner in CAD and really a NOOB, sorry for that 

→  I upload the CAD -  Step File , feel free to make it better.

→hopefully there are some Professionals who can make a better design out of my bad one.

But, 

-->i like my design and it works great for me and i already respool hundreds of filament rolls, 

 Just a little favour

>>>Less then 10% of downloaded Models get a like.

→ If you like the design, it will be nice if you click on the like button and maybe share your print. 

I love this awesome project from
Miklos Kiszely, thx a lot for this design)

But  in my opinion needs to be improve. 

So I improve a lot things and found a lot improvements wich are already great I upgraded these also and bring it togethter into my improved Spool rewinder. 

The Awesome Filament Spool Winder

its possible to use it manualy one or elecric driven

both design are avail in this post.

Main Changes are:

- Mainbody with 3 additional bearings , so it is a lot more stable and reliable

 -one additional bearing at the Main Body to guide the middle gear better.

-one additional bearing at the Main Body to guide the axle much better.

-one additional bearing at the filament carriage sled worn gear assembly 

-guides with slides at filament carriage sled to guidevit better and avoid a lift up

-Spindle with Bearings, to avoid exessive wear and smoother work 

-i uploaded 2 Spindles one normal one for Bambu spools and a shorter for Sunlu and similar…

-additional threaded Inserts on the top to fit the cover for the filament spool axle

-the holes in the base of the main Body to fix it on a Table or some other thing..

-the heavy axis 45mm with steel insert - put into the axle a 4mm hex wrench and cut it.. if used manuell 

-Filament Guide with M3 threaded Inserts and longer slides

-the Spool center adapter to use every spool with inner diameter from 40 to 75mm for the spool holder

-some M3 threaded melted inserts are added for a better usage.

The Bearings for the Spindle are 6200RS2, 

I ordered these from amazon 

TAIANJI Kugellager 10mm x 30mm x 9mm Double Shielded Rillenkugellager Metall Kugellager für 3D drucker, Skateboard Roller Inline Skates etc(6 Stück) : Amazon.de: Sport & Freizeit

 but you can also use the Printed ones which i added it works also good if your printer is good calibrated.  

Spoolaxle with bearings 

As Pinions and axles i used the great improved axles from Damian(thx for these)

and i upgraded the Motordrive unit from Bird2Barin(thx for these nixe design) to fit it better to my upgreated Mainbody.

To Bring it together I screw The Main Body the Unwinder Body and Motorunit on a Wooden Board 22cm x 50cm x 1,9cm
