Measuring tool for knitting needle

Ball of Yarn - measuring tool for knitting needles
One thing that people who are knitting a lot needs to have in hand is a measuring tool for knitting needles. I designed a ball of yarn in Inkscape. Didn't do any offsetting here because the needle needs to go through the hole and not to get stuck in it.

I think the test pieces turned out quite nicely. I used the standard settings in the laser cutter.
