I appreciate the effort to get those files online.
I made some modifications to one side of the blade. I removed the buttons and made it sit flat on the print bed.
No Supports necessary
0.2-0.1 layer thickness depending on detail
I printed at 80% scale on Cura with my Anet A8
Printed with the gorgeous Prusament Galaxy Black
Note: Because I printed this at a 45 degree angle on the bed to make it a good size I needed to adjust my Cura Top/Bottom & Shell pattern to [0,90].
