DIY Power Bank Case

thingiverse

I decided to make my own High Capacity Power Bank. For this, I used 3 6,000 mah 18650 li-ion batteries(for a total capacity of 18,000 mah) and a usb and micro usb board to charge the batteries and to charge my phone with the power bank. I made this case to fit 3 of those 3.7v batteries and there is room for wires and room for the Circuit board. It is a nice and compact case with easy access to thte batteries and board if needed. You may have to sand out the hole for the USB port a bit depending on the size but most likely not as they are all usually around the same size. I also did not make a hole for the wires from the batteries to the USB so you will have to cut that out as well. Hope you all enjoy this and feel free to leave a tip because I am a High-school student making these for fun and I am trying to save for college. Thanks:)
