CR2032 adapter for Pokemon Go+ on powerbank (non-destructive)

thingiverse

I created a CR2032 adapter to run my Pokémon Go Plus off a power bank instead of replacing it daily with a new CR2032 battery, making it cheaper and more sustainable. This adapter can also be used for other devices that use CR2032 batteries. The negative pole features a recess for a standard M5 washer and a through-hole for the lead. The positive contact is located on the outer edge of the adapter, where I connected thin metal sheet approximately 0.1mm x 2mm x 64mm using a micro buck converter set to 3.3V. This converter is connected to an old USB cable supplying 5V power. The Pokémon Go Plus does not draw enough power on its own to keep most power banks running, so it's best used with a dual outlet to charge the phone at the same time and maintain power flow. I've been using this adapter for about a week now, and although it looks a bit rough, it works perfectly so far. I even printed a Pokémon Go Plus case with an extra back lid, but botched the whole thing after soldering everything together, as a small hole was not enough to fit the leads through.
