Check out the Sew Easy! Group at Thingiverse. It is all about sewing supplies, 3D printed fashion and tools related to threads and fabric http://www.thingiverse.com/groups/sew-easy"

This is a spool holder for big thread spools to be used directly on the sewing machine, without having to wind the thread to another smaller spool.

I am always keen on seeing people use my designs, so let me know by sending pictures of your makes!!! :D
