Spool Winder Upgrade with bearings from Sergiu’s model

Model Overview & Print Notes

  ***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)
