Ender 3 dual-Y stepper mount V1

Long story short, I made a bracket to mount a second Y-stepper to the single belt on my Ender 3. I was able to push speeds to over 200mm/s and 12.5k accel with Klipper

Work in progress: this is a rough, not well refined version; tolerances aren't the greatest and it's a finicky mounting system.

If I ever get around to making V2, I'll take better pictures
