M3D Raspberry Pi A+ Mount

EDIT:

- Changed the size and height of the mounting posts to improve mounting and printing.
- Added a groove in the side which allows access to the SD card at any time.

This is a part of my power-reducing project involving the M3D, a handy mount for placing the Raspberry Pi A+ on the M3D frame!

But why would someone want to do this?
Well, considering the print spooler program for the M3D is required to be running the entire time the M3D is printing, the computer must be constantly on.
For me, running a pretty heavy computer setup can run my electricity bill pretty high for a simple print.

the M3D can be completely ran off of the Pi! Just send the files via Wifi and use the Pi to manipulate and print the object.

So far this design is only oriented for the A+ model. If I see that t
