A la the famous Flat Stanley, print a 3D model of something (or someone) you find meaningful. Ttake your new object on a journey around whereever you are and document that journey in photographs. You can find lots of great models at http://thingiverse.com or you can make your own using a CAD program like TinkerCAD.
For example, you might make your own Stanley (or even this dancing Ganesh) take him with you to the supermarket and photograph him helping you choose which brand of cereal to buy. Or you might print a skull and photograph strangers posing with it as Hamlet lamenting poor Yorick’s demise.
