Adafruit Micro LiPo Charger Case

thingiverse

This is a simple case for the [Adafruit LiPo Battery MicroUSB Charging chip.](https://www.adafruit.com/product/1904) I personally didn't feel comfortable having a charging circuit completely exposed, and this gives a little bit of a protection buffer for it. All that you require for the case are a set of (x4) M2 x 16mm Screws (14-15mm should work too) and (x4) M2 Hex Nuts. The chip goes inside the body of the case, the lid goes on top, and then you tighten everything together with the M2 nuts + screws. This allows you to remove or replace the case as necessary. No supports necessary. I recommend PETG over PLA because of the greater heat resistance, particularly if you intend to modify the chip up to the 500mA charging rate.
