Vive tracker battery puck with haptics

# I have remade this to be smaller. please consider building [this puck](https://www.thingiverse.com/thing:6801058) instead, as its smaller and much lighter, with still a notable increase in runtime

i needed an excuse for a new soldering iron to feed my keyboard addiction.

This is a battery puck made specifically for HTC Vive trackers, though Tundras and Etee support is planned eventually.

It supports [Haptic Pancake](https://github.com/Z4urce/VRC-Haptic-Pancake), and is the lid is a remix of the plate provided. Dual motor for if haptics feels weak despite being full power.

- 3.0s to 20-24 hours from 6.5-8 hours
- Tundras to 32-35 hours from 10-11 hours
- Etees to 16-18 hours from 5-6 hours
