Portable power supplies (or battery packs) do not allow the user to chose which power source they want. By separating the charger from the transformer unit, users have flexibility. To enable such users to easily carry around the unit, we're designing and sharing 3D prints for the cases that hold LiPo batteries.
Battery CaddyWe made caddies to hold LiPo batteries for your own battery pack. The charger output is USB-A, 2.7A per port, 50W total.
The STL files for the above are on Youmagine, and we'll be adding larger battery case designs.
Build detailsBuild details here: Pirl Charger update.
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.
Once the bracket and caddy are printed, you can connect the two using the press-fit slot. The bracket is printed separately so that once more caddy sizes are available, you’ll be able to swap them out without having to re-print the bracket.
Internal dimensions3.4" x 1.4" x 1.1" or 8.7cm x 3.5cm x 2.7cm.
