~ No supports needed, cap is a separate element for i.e. easier print. Takes total of 21 min and uses around 3 grams ~

Hi,

This is my first project created when I was facing an issue with my other hobby - sewing.

It can be used as a spare spool for thread rewinding (normal machine's function - as shown in the photo). I.e. it's super useful if you have only 1 spool with a thread of a particular colour, but need more spools of this colour for double needle or overlock etc. and don't want to or can't buy more identical threads, then you can print this bobbin, rewind the thread and enjoy additional supply.

Basically it works the same as rewinding for bottom small bobbin but allows to put much more thread on it.

I designed it for my Janome 1522, but I'm fairly sure there's a lot of other machines it will work well with, it needs to be tried out (I will be happy to get feedback if it works on other models).

You can use the cap to snap and hold the beginning of a thread when putting a cap on a spool and you don't even have to hold it with hands while starting rewinding :) I can share vids if there's any confussion

In case of any question I'm happy to help
