Update: Nov 19 2017 Updated bottom case with pads with slot added for easier removal of pads Nov 4 2017 (V2.2) 1. removed some material on top cover to clear solder blobs. 2. add top and bottom cover files without corner support. Just in case your printer can handle it. Less cleanup after. Here is my version of Portable power bank phone charger. I wanted high capacity and portability. I couldn’t find any others on Thingiverse when I started, so I made my own. After working on this for 3 months (Having to stop due to other projects) I saw one posted here. – Wow, Great minds think alike! Mine is not any better – just different implementation. And while you may want one, it would be cheaper now to get the case and module in the kit offered by Banggood.com.
