The door symbol did so well in the Shapeways store that I decided to do some more items. I have actually been selling the keychain since last year. Just added the bookmark recently.
In all honesty, the keychain has been selling really well, while the bookmark... zero sales. My guess is that the keychain is more utilitarian and people actually need it. The bookmark not so much. And also people don't read books anymore, it's all digital nowadays. 
Like before, you can get them here: Shapeways store

Fantastic presentation by John Green, made me realize the importance of belonging to a community that challenges me for growth. Brilliant. Thank you John.

Airbnb guests sometimes have trouble finding the home they're staying at. So why not make it easier for them to find your nest, after all, in the US all the houses look the same right? So I decided to create this House Symbol that you can place with your house address. If you are interested in getting your own, just go to my Shapeways Store to get one, and proudly let the world know you are part of the Sharing Economy!

I have always felt that playing games on a smartphone or tablet was very limiting due to the controls on a touchscreen. So I thought, why not just bring a known interface that works on your mobile device? That's how I came up with Keybars! Think of it as a game-pad that clips to your mobile device, giving you buttons that add tons of functionality. This is a product that many people would love to have, not only for gaming but also for everyday tasks like copy-paste-selecting, etc.

Now, been an artist and not an engineer, I submitted my idea to Quirky.com because they're pretty awesome at helping inventors. If you like this idea, please vote it up, as Quirky uses the voting system to move ideas forward. It's a great system, but it requires people to get involved, Besides, I'll try to keep the price on this product low, so everyone can enjoy it!
