Thread Spool with Clamp for Sewing Machine

In our Hackerspace [Chaostreff-Dortmund](www.ctdo.de) we have a Singer Professional XL-1000 automatic sewing-/stitching machine.

We got some very big spools with high-quality thread, and even machine-lathed an adapter for them, but the tension on the thread was too high simple because of the mass of the big spools. The thread often cuts off and dozens of needles have been broken due to that so far. With the new spools no problem, no broken needles.
