I had to reshape a little bit the original to fit the blades I have over here, with a little narrower shape an 3 slots, so neither the shape nor the hole for the screw was fitting.
I used Blender for reshaping. Scan the blade, put as a background image and working on orthogonal top view, edit the object selecting a moving the vertices to fit the blade, easy and fast.
The design is very nice and it works like a charm.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
