Greenmaster 828M Treadmill Safety Key

thingiverse

I'm replacing a broken safety key on my Greenmaster 828M treadmill, as shown in the image. The old key snapped off, leaving me searching for a replacement - but none were available. To solve this problem, I decided to create a new key using Fusion 360, learning the software's capabilities along the way. After designing the key, I used Cura to slice and print it with excellent results.
