How to Build an Open-Source 3D-Printed Trackball (That Lasts Forever) | Ploopy Classic DIY Guide

Hi everyone, I wanted to build a Ploopy Classic Trackball and found there wasn't yet a full build guide video anywhere on the internet. Figured I might as well make one. Enjoy! I followed the assembly instructions (linked below) on ploopyco's github. They're very detailed and entertaining, and I hope my video can act as a companion to them while you complete your build! I tried to include as many of said details as was reasonable while keeping the video (relatively) short. Also, I've determined via a Reddit thread that my sensor being presoldered was uncommon and not to expect it in a typical kit. It was just a lucky situation. Let me know if you have any questions or criticisms in the comments. Apologies for the camera focus issues - I was more focused on building than filming at times. Maybe I'll build more things in the future! Thanks for watching :) Links: Ploopy Classic Trackball kit (I build Revision D): https://ploopy.co/shop/classic-trackb...
