Raspberry Pi A/B mount for 20x20mm Misumi Aluminum Extrusion

Since I use OctoPi/OctoPrint to control my 3D printer, I wanted to create a mount for the Raspberry Pi so that I could keep all my electronics under the floor of the printer. I also run a voltage regulated that takes the 12V that my controller board runs off and steps it down to the 5V for the pi. That way, all I need to do to print is just plug in a single power cable, navigate a browser to the OctoPrint page, and voila!

While this was created for Jasonatepaint's Aluminum Extrusion Ultimaker V2, it should obviously work with any 20x20 aluminum extrusion.

It also should be noted that (as far as I know) this only fits the original RPi's (the model A and the model B). I've uploaded the .ipt Inventor file if you want to make any tweaks to it.
