Update: November 23rd, 2016 - New version - This updated version now includes chest and knee rests for supporting the O'Cello while playing, and an adjustable end-pin. This is no longer a prototype, it is now ready for anyone to print and play.
Update: July 10th, 2017 - Improvement to part 6 - Some people have found it difficult to get the tuning keys to attach because the walls of part 6 were too thick. I've narrowed these walls slightly to make it easier to screw in the tuning keys.
Update: May 8th, 2018 - Original files - To make remixing the O'Cello easier I'm releasing the STL files for the major parts in their original orientations and positions. The STL files included in the download above are rotated so that they have a flat edge on the build plate, which is perfect for 3D printing but this makes them harder to modify. Download this zip file to get the parts in their original orientations and positions if you're interested in making your own remixes.
The cello doesn't need to be painted, but it does look nice with a black fingerboard. I spray painted the front of the fingerboard with semi-gloss black acrylic. Use masking tape to prevent the spray paint from hitting the sides of the part, and touch up any over-spray with white acrylic applied with a paint brush.
