Print yourself a pokedex, and fill it up with pocket monsters of your own invention!
Print out the included SVG (or PDF) on a normal, 2d printer and use them to document all the creatures you can imagine.
There are a lot of parts to this print, but everything except the back and cover are quick and easy. Everything is broken up into separate pieces so that you can print them out in different colors. See below for details on how all the parts fit together.
Note that the "coverButtons" stl has a sprue connecting the individual buttons- I recommend gluing the buttons to the cover (with CA glue) as a single unit, with the sprue facing outward. That way, all of the buttons will be kept in alignment. Then, once the glue has fully set, snip off the sprue with a sharp knife.
You'll also need a rod of some sort to finish the hinge- insert it through the holes in the back and cover to connect the two parts.
