Modular Synthesizer Control Keyboard

Multi-part design for synthesizer controller keyboard, the DIY synthesizer designer's dream! Modular design allows you to print as many sections as you need. Need another octave of keys? Print all you want?  Want 5 modulation wheels? You can do it! This design has many useful features for the DIY synthesizer designer! The front panel has a grid embossed on the back for easy drilling of holes for knobs and sliders; never worry about the drill sliding away from you again! The bottom includes mounting holes for screwing down circuit boards. The edges have grooves in them so that the parts will not jump out of alignment. The whole design is designed to be fastened together at the ends with threaded rods through all of the parts. The parts are currently designed at a very small scale so that you can scale it up to any size that you need. The file "keyboard6.stl" is an exploded view with all of the parts, and is only for an overview of the design, not for printing. Note: A lot of folks were having trouble with non-manifold geometry in the original version, so I used a tool to repair all of the files. This might lead to some of the screw holes being strange, but I think it will probably print correctly now.
