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

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!
