This is a game controller that hooks to a Makey Makey. The handles are in normal non-conductive PLA and the touch pads are proto-pasta conductive PLA.
A couple of notes on making:
1- This pretty much requires a dual head printer, if you can figure out how to do it on a single let us know!
2- The dual head technology is so-so and the head not in use tends to drag over the print leaving lines of one material in the other. This can "short" buttons together. Check them with a volt meter, if there is any continuity, drill a little hole through the black drag marks to break the connection.
