Updating the Etsy store

Cleaned up some items in the 3D Printing Professor Etsy store, and added a few one-off items to clear out my inventory. First of all, a few Ur boards left over from the kickstarter. But secondly, and more exciting, at the request of a few people, I am making signed copies of my book, the Beginner's Guide to the 3D Printing Galaxy are now available.

I really don't know how to promote this. I know I should be all "Now you can get this awesome thing" but it's just so surreal that anyone would even want it. So, thank you for requesting it. You guys are awesome.
