Much stronger rewinder

If you like this model and use it please upload a like, it really helps others find it!I added more magnets, and made a ‘magnet pen’ that can be driven with a nutdriver or any ¼" electric screwdriver. Most of my filaments have a pretty long reverse bowden so sometimes i didnt quite have enough torque with only 1 n52, and forget the first few boxes I made with amazon magnets (n52 lol more like n30 if we're lucky). Thus, I made this using 4 magnets on the spool holder axle, and another 4 on the rewinder side. the problem now becomes the grip of the axle on the spool of filament, especially with plastic spools. Still working on that. To assemble, you need 4 10x5 n52 magnets, for each half. if you look at the static photo of the part in my screwdriver above, you'll see two have paint marks, this is because you want them assembled with the magnets poles oriented like this for best results: N S S NThe electric screw driver I'm using in the photo is a fanttik S1 Pro from costc
