Adapter côn chỉ ren (Thread cone adapter)

Adapter to fit various large thread cones (4500m, 5000m, 9000m, 10000m etc) to your thread stand or sewing machine, as long as it has a spool pin long enough to support it, and that pin is smaller than ~6mm diameter, it will fit.

I designed this for the Prym thread cone stand, as I didn't think the original pin it uses were a great way to support larger thread cones.

I have only tried it on a handful of different thread cones I had on hand, but it works well on all of those.

It should be printed on a material that allows for some flexibility and doesn't creep. I used PETG with great results. It will probably work in PLA, but lose spring tension much faster over time.
