Circuit Playground Yo-Yo

thingiverse

Update: Adafruit created a version of this project that doesn't need hardware! Check it out here: http://www.thingiverse.com/thing:1766385 Create a programmable yo-yo using Adafruit's Circuit Playground and these 3D printed parts. The assembly is snap/press fit. For the full instructions, check out the Google Doc linked below. For scaling/dimensions - scroll through the photos above. All dimensions are in inches. To print this project, you'll need to print two yo-yo body parts along with two snap rings. You'll assemble the yo-yo using an M5 nut, spacer, and hex head screw. If you press the nut and the hex head screw into the plastic while it's still warm, it's a lot easier. Forgot and let the print cool? No problem, just use a little more muscle.

The most challenging parts are the radius on the bottom edge, and the overhangs. Luckily, both of these are cosmetic. Also, I have printed this at 30 and 100% infill. I actually prefer the 100%, because it gives a good weight to the yo-yo. But if you like a lighter yo-yo, keep it lower! Post-Printing I'll be adding assembly instructions to my documentation, and I'll copy over here. Most of the parts self align, but I'll try to be as clear as possible. For now, this is what I've got: https://docs.google.com/document/d/1D5e25YyS03JxVD4htC4jWKgDW4xaqA6sHQgkYaIvEoA/edit?usp=sharing How I Designed This CAD via OnShape: https://cad.onshape.com/documents/a10dec4ede7ddb8cb4bf5b27/w/f8c0332f02fca9a2d04ad0e7/e/16cf2d2a2c0f6cde0a206a35 Edit Log 7/29/16 6 PM - Added files 7/29/16 10 PM - Fixed small misalignment of board alignment pegs. Parts printed before file fixed should still work.
