Cheers! Yep, have been fighting with Fusion 360 on this longer than I’d like to admit 
Assembly, mount Core XY belts
Uploaded 5x sped up recording of me figuring out how to assemble the CoreXY belts. Slow playback to 0.25x if/when interested in understanding the audio of me ramble/explaining details. Audio isn’t great at 0.25x but may help with trickier steps.
The theme song for this post is “Yakety Sax”, open in separate tab while watching above video for maximum user experience.
Feedback/suggestions on better assembly sequence and techniques appreciated, cheers!
6/13 Update: Bought some discounted I2C to NeoPixel driver boards via Adafruit’s weekly 50% off stream, might use to help quickly setup power injected gratuitous lighting.
