CPAP Headboard Frame

This is a simple frame to hold a CPAP or BiPAP machine on top of your bed's  
headboard to maximize the usefulness of whatever hose length you're using.   
Since machines vary widely, you can tweak and re-render the OpenSCAD file for 
the dimensions you've pulled off your machine and your headboard.  (The machine 
dimensions given here are for a ResMed AirCurve 10.) 

You could either print two or three of these in the default 1" width, or  
you could (with a sufficiently tall print volume) set frame_width to the  
width of your machine to make a shelf.
