small spool 200gr/500gr/1kg

This thing was created with Tinkercad. Edit it online at https://www.tinkercad.com/things/0V3bypctz21. I made adjustments to the tamel55 small spool, tweaking the threading and holes for easier winding. Additionally, I added a coupler that's perfect for spools of 1kg or more. The original version was a bit flimsy, so I strengthened the rims by about 4mm. My previous version kept breaking when the spool reached halfway capacity and needed to be repackaged in a vacuum-sealed bag. With one coupler, you can wind up around 500 grams. Use two couplers, and you'll likely reach 1kg. I printed with 100% infill. The female part weighs about 45 grams, the male part is roughly 40 grams, and the coupler weighs approximately 30 grams. The layer height was set at 0.35/0.4mm, with a 0.5mm nozzle. The threads are quite large, making them easy to fit despite the coarse layer height. When tightening for the first time, it may be difficult to get everything to align properly. However, after unscrewing and rescrewing a few times, you'll find that it gets easier with each iteration. Be careful not to over-tighten, as this can make it impossible to unscrew again. I used PLA, which tends to stick when screwed or unscrewed too tightly.
