There are 3 STL files you’ll have to print. The first, “pirl_bracket.stl”, is the part that grips the charger by its perimeter. The second, “pirl_caddy.stl”, is the part that holds the battery pack. The third, “pirl_caddy_cap.stl”, is the lid that covers the battery pack after it’s connected.

The STL files are on Youmagine, and we'll be adding larger battery case designs.
