Battery case for Fairphone FP2

thingiverse

I quickly got fed up with the lack of power my FP2 experienced, so I bought a KiwiBird 5000mAh Battery case for Samsung Galaxy S7 and designed a custom case to fit the hardware on my FP2. If you buy a Kiwibird (for example here: https://www.amazon.co.uk/dp/B01KUAHO3U/?th=1) and some M2.2 pan head tapping screws (example here: https://www.amazon.com/uxcell-M2-2x9-5mm-Phillips-Tapping-Screws/dp/B01DIL1RH2/ref=sr_1_7?keywords=pan+head+tapping+screws+m2.2&qid=1549649846&sr=8-7), you can assemble the KiwiBird (keep all electric parts together!), print this case out (Scale to 100.6% for it to fit) - I used PETG-S from Kimya, and then put a 1€ coin in the hole as heatsink. Next, assemble The Kiwibird with the printed case, remove the back case of your FP2 (keep the front part with the buttons), and put your new case in place. Charge and enjoy! Features include adding 5000mAh external battery to the phone through-charge and data link included, no safety issues because it charges through normal USB port, external battery has its own safety circuits, and an added heatsink to help evacuate CPU heat. I'll post more information about this project in the Fairphone Forum (https://forum.fairphone.com) in the next few days.
