I've put many of the models from the book online for anyone to download for free. (Though of course the idea is for you to use the book to learn how to make these models on your own!)
In case you haven't looked yet, here is a summary of all of the models in the book. If you want something from this summary that doesn't appear on the download list below, please let me know and I'll add it.
You can find these download models on a relatively new website: http://3dfilemarket.com. This UK-based site was set up recently by high school teacher Phil Cotton, who found me via the book release announcement from 3D Printing Industry.
Here's what Phil wrote when he contacted me about getting my models on his site:
My background in 3D printing stems from teaching it in school, and then winning a 3D Print Show Award for Educational Excellence. Before this I was a Industrial Design graduate from Loughborogh University in the UK. As a hobby I was designing for Cubify, and when they ended their marketplace I wanted somewhere else to host my models. Also, I had shown my high school CAD students that they could get paid for good models, so it turned into an enterprise / business aspect of teaching.
I can see your book becoming a very big educational feature - students will be able to self-teach at home at their own pace, and not be constrained by lesson timings. Independent learning is a massive thing many student lack at the moment.
So here are the links to download my models:
DNA (my favorite!)
Jewelry Box (with dovetail joints, no glue needed!)
Penrose Rhombs ("fat" and "skinny" tiles)
Die with Numbers (no dots here!)
Enjoy, and please feel free to share your own 3D printing models with me!
Anyone can design anything in 3D! http://www.3dvinci.net/
