Printable Sewing Machine Bobbins

The better half wanted some bobbins making but I could not find any for printing without needing support. After getting my head round some 3DCad I came up with these for my very first project (published anyway)

They are definitely a work in progress and will look to update when I get feedback off her.

They should firmly push together and if necessary a drop of superglue to fix

Printing in PLA @ 200C, 50C bed, 100% infill, 0.2 Z feed and slow speed On my
Aworldnet A600 but obviously experiment to get best results

What no Comments? Must be really good or really bad LOL
