Description
The original file that I took this from was completely unusable. Re-created it so it works and is printable.
Flat on one side prints great and is a great, and cool, letter opener.
Recommend 0.1mm layer height for best blade toughness. If you use 0.2mm you'll likely need to trim off the first layer from the blade edge.
