My first contribution on Thingiverse and first design. This is a 3D printed USB Power bank based on MakerHawk 18650-Board (H961-U v3):

Adapted a touch sensor instead of the build in tactile switch of the board to display charge info. Used this touch sensor:

The bottom of the case is designed to hold 6 18650 cells (more could be packet it). In my case, I used 6 old laptop cells and connected them in parallel (as the board specifies).

The top and bottom parts combine using clamping pressure. Caution here as once put together may be difficult to take apart.

IMPORTANT: I have not designed any side openings for the board tactile switch or the Lightning opening as in my situation, they are not used.
