Music rest for Alesis and Casio digital pianos (laser cut + 3D print)

This is a music rest for digital pianos that have two round holes for a music rest. The default dimensions (which you can change in the OpenSCAD file) are for 6.1mm plywood, 5mm steel rod, and 51.5cm spacing of the mounting holes on the piano. This spacing occurs on the Alesis Recital and presumably other Alesis digital pianos, and perhaps (check before cutting) the Thomann DP-26 and SP-5600. I also prepared files for a number of Casio pianos with 19.5 inch spacing of the mounting holes. A website says that this spacing occurs on the models CDP S100, S110, S150, S160, S350, S360 and S90, but I have not tested any of this.

The project is involves laser cutting plus a few 3D printed gizmos.

You will also need a 5mm diameter steel rod bent to the correct shape and some wood screws that are about 12.5mm long.

If you have large enough plywood, you can cut back-full.svg and shelf-full.svg, print two or four clip-thru.stl files and two clip-end.stl files, and assemble. The clips hold the steel rod to the back of the rest.

If your plywood sheets are smaller, you may need to cut back-left.svg, back-right.svg, joins.svg and then either shelf-full.svg (if it fits on your plywood sheet, e.g., diagonally) or shelf-left.svg and shelf-right.svg. Glue the joins strips to join the left and right halves together.
