Sewing Thread Winder (including non-AMS version)

This design is for small thread spools used with household mini sewing machines It can transfer any thread spool to a small core This means when buying thread spools, you don't have to worry if they'll fit into a small sewing machine, giving you a wider selection

Installation Instructions:

If you don't have a screwdriver at home, you can print the screwdriver accessory included in the files, but be sure not to use too much force, don't twist it off, it can barely be used by turning it slowly (a flathead screwdriver is still recommended)

Instructional video:

Regarding smoothness:

Several versions were tested, and the current version is relatively smooth If printing imperfections cause it to be less smooth, you can add lubricant yourself

Sharing the original intention behind the creation:

My wife recently got into sewing, and a while ago, she stumbled upon macaron-colored sewing thread spools on Taobao and placed an order without checking the size

She was stunned when it arrived The thread spools were too big, and her sewing machine couldn't pull them at all

But the colors were so lovely she couldn't bear to waste them, so she had to manually transfer the thread onto small cores

Seeing how much effort she put into winding them, I wondered: Isn't there a small household tool for winding thread I searched on Taobao, and there really wasn't anything for winding thread onto cores, though there were many for winding bobbins

After all, sewing thread itself isn't very expensive, and the cost of a machine would buy a year's worth of thread, so no one was willing to make such a thing I also looked through MakerWorld, and all the machines were for winding thick yarn, with structures completely unsuitable for small thread cores

Alright, it's better to rely on myself than others, so I decided to make one myself I thought about it and redesigned a structure, and to my surprise, the first test was quite decent

I adjusted the gear ratios a few more times, and the functionality was perfected

Finally, I polished the appearance a bit It's very easy to use, and seeing my wife no longer struggling to manually wind thread

This sense of accomplishment and emotional value truly cannot be bought with money
