Easy Sewing Thread Winder ■ For Coverstitch and Overlock Machine Threads, Spooling Machine

This attaches to the bobbin winding mechanism of your sewing machine, allowing you to wind smaller spools of industrial overlock thread and other threads.
It is compatible with thread spools up to 6 cm in height, such as empty Chappé Spun (#60, both 200m and 700m).

[User Reviews (personal opinions)]
☆ I managed to get by in an emergency when I ran out of just one spool of overlock thread using this.
☆ It's super fun to wind the thread!
☆ I find it very convenient for giving thread to students at my handicraft classes.
☆ It requires some technique, like using a pen to wind evenly, but it's useful because you can wind overlock thread in smaller amounts than on a bobbin.
☆ It's so convenient and fun to wind that I even posted a video on social media!

[Notes]
○ When attaching to a domestic sewing machine, align the spring on the bobbin winder shaft with the indentation inside the hole (located behind the mark on the surface of the main unit of this product) until you hear a click.
○ You can reduce wobble and achieve better balance by wrapping masking tape around the shaft or by inserting a cut rubber band between the shaft and the hole.
○ It is made to be a snug fit to prevent wobble (we have confirmed it can be used with several sewing machines, but if it is too tight, carefully widen the hole with sandpaper wrapped around a wooden chopstick).
○ We have added an indentation on the bottom so it can also be used with some industrial sewing machines, such as the JUKI Spur.
○ Balance the thread spool and secure it with the nut.
○ The product may break if the nut is overtightened.
○ Please use safely at a sufficiently low speed (less than 60 revolutions per minute).
○ High-speed rotation can cause breakage and ejection.
○ Materials: Base = Polylactic Acid (PLA), Screw = Iron, Decorative Nut = PLA
○ Estimated lifespan: 30-50 uses
○ Use a pen or similar tool to move the thread up and down for even winding onto the spool.
○ May not be usable with older sewing machines that use thin plastic bobbins.
○ To prevent loose winding, properly use the bobbin winder mechanism or apply appropriate tension with a sub-tension device.
○ Weight: Approximately 20g
○ Condition: There may be fuzz or printing marks characteristic of 3D printing.
○ Simple packaging using recycled materials such as empty candy boxes.
○ Thread, thread spools, bobbins, sewing machine, instruction manual, sandpaper, and receipts are not included.
