Honestly, I’m not sure what to name this thing. But, “art piece” seems appropriate. It doesn’t really do much, but it pretty neat to look at. I’ve had a piece of birch plywood laying around ever since I got the Othermill back in March of this year. I just got some florescent pink acrylic, too. Thinking of what to do with it lead me to make something with a Pokémon / Pokéball logo on it. I figured, I ought’a mill something pretty simple and put some more hours in learning CAM tools in Autodesk Fusion 360. I used a total of 3 bits to mill this (a 1/8″ end mill, 1/32″ end mill and a 80º engraving bit). In Fusion 360, I only used 3 operations (Pocket, 2D Contour and Engraving) – Pretty straight forward and nothing too fancy. I hoped the acrylic would have a friction fit into the cut out on the birch, but the tolerances was a teeny bit too loose. In retrospect, I think an offset of 0.1mm would have had a better fit (the Pokemon logo cutout in the birch is 0.2mm offset than the acrylic). Better to be loose than too tight, in my opinion – Mounting tack holds the two pieces nicely together.
If anyone has any questions or would like to see a Layer by Layer tutorial on how I setup the CAM tools in Autodesk Fusion 360, drop me a comment below!

The Othermill is a portable, precise milling machine that allows you to create 2D and 3D objects out of durable materials, such as wood, metal, and plastic, using digital designs. It’s one of Lady Ada’s favorite tools, and we use one at the Adafruit factory every single day to prototype new designs, create testers, and experiment with fun new materials
