Spool Winder Upgrade with bearings from Sergiu’s model

***Update 01/2025***

Considering some community member requests, I did modify the base1: 
- to reinforce it while printing
- to reduce the body shaking while spooling manually
- to reduce the structure eight under 240mm for other machines.

Hi everyone.

Like many of you, I use an AMS and as much of you, I got trouble with carton spools. So, I needed a spool winder for filament transfers.

After looking at all the existing models, I finally chose Sergiu’s one. It seemed to be pretty good, and it is so far.

However, after a couple weeks I had to admit that although Sergiu’s spool is super, I could improve it. Though I dreamed of a major upgrade… adding ball bearings on the axis.

THANKS TO SERGIU who agreed on transferring to me his own original 3D files to be directly reviewed onto my 3D software, I could start the remodeling process.

So…

After long hours reviewing, print pieces, test, modify more, then again print, test… etc. I finally got my new winder.

The improvements are:

- 2 ball bearings on each axis. Quiet, smooth and fast. No oil needed.

- no more need for sanding the holes after printing. No dust.

- around 15 ½ hours printing for the full version. Not 36 hours = time saving.

- feet not needed anymore. But you can still add them, my model kept compatible.

- consumes less than 450g plastic needed. Half of the original version.

- full PLA+ made. No need for abs or petg.

The result is a full 1kg transfer in less than 1mn50s… manually. See by yourself

The basic printing setup is:

- PLA+ at 0,20

- 3 walls,

- 4 bottoms

- 20% infill

- no support needed

Don’t forget to PAUSE & INSERT THE BEARINGS on the axis. Bearings 12mm type 6901 (12*24*6)

- Worm axis pause at layer 127

- Reception axis pause at layer 97

- Doner axis pause at layer 69

Another three 6901 bearings will be needed:

- 2 for the middle gear

- 1 to insert directly on the winder body for the worm axis tip.

The 2 last bearings are 15mm type 6802 (15*24*5) needed to be inserted on the winder body for both the reception and the doner axis tips.

 To resume, you'll need to buy 8 bearings apart:

- 6 pieces of 12mm diameter - type 6901 (12*24*6)

- 2 pieces of 15mm diameter - type 6802 (15*24*5)

The improvements are:

- 2 ball bearings on each axis. Quiet, smooth and fast. No oil needed.

- no more need for sanding the holes after printing. No dust.

- around 15 ½ hours printing for the full version. Not 36 hours = time saving.

- feet not needed anymore. But you can still add them, my model kept compatible.

- consumes less than 450g plastic needed. Half of the original version.

- full PLA+ made. No need for abs or petg.
