Raspberry PI Zero W mobile case w/battery

thingiverse

The Raspi Zero W is a remarkable little machine. To make it more portable, I added several key components: a 3.7V 1500mAh LiPo battery with protection circuitry, similar to the one available on eBay for a competitive price; a charger circuit that can be easily integrated into my project using a TP4056 module; a 5V step-up converter from Pololu that efficiently boosts voltage for my device's needs; and a compact USB hub stripped of its casing to save space. To complete this build, I also gathered additional materials: a mini toggle switch, various lengths of 2.2mm screws, and some wire for connecting everything together. The USB hub and 5V step-up converter must be soldered carefully onto the underside of the PI Zero, following the same process outlined in this instructable. To ensure a watertight seal, I recommend applying hot resin to the solder joints after they have cooled down completely. Unfortunately, I am still waiting for my USB hub to arrive, so no photos are available yet. The 3D printing process was carried out using PLA material at a relatively low resolution of 0.2mm and 0.4mm nozzle size, resulting in an aesthetically unappealing print quality but sufficient structural integrity.
