Retro Filament Spool Keychain

I found Heliox's "Beautiful Mini Filament KeyChain" on the Adafruit news feed and thought they were completely amazing. While I have a couple of spools that look like Heliox's modern spool design, the majority of my filament stock is on the older, chunky black spools of yesteryear.

I decided to create my own version of the keychains with the retro (can we call it that yet?) spool design from when I started 3D printing in 2011.

I'm still learning best practices for Fusion 360, so the design could be a bit more parametric, that being said I've included the .f3d and .step files if you'd like to make changes.
