24 Pin Knitting Loom

I have not printed this yet. I'm planning on printing this so it is 14cm in diameter, not including the yarn knob. There are 24 pins and each pin is 1cm wide. I tried to make this as close as I could to the loom used in this video: https://www.youtube.com/watch?v=sIYrx8Zs7v0#t=39
