UPDATE: VERSION 1.3!!!
I rounded over the back and made hanging slots so it's easier to take on and off the wall. I also added some more washers if you need them and I've put 4 holes on the top plate that can be used with standard 3" or 4" cabinet handles to make it easier to carry. The holes could also be used with a undiscovered future hopper design to keep it in place. Plus some other misc. tweaks to make things easier to move parts around. .03mm here .03mm there. little things.
This project has gone through a major design change for the better and now has none of the original design elements from the 1st version. So be sure to use this version if you want to make one. I made the case smaller, adding a fan mount, changed the hardware requirements so there is no drilling, gluing necessary and it now works as both a desktop or wall mount design.
It all started when ianjohnson made a vertical hopper to make extruding easier and I thought it needed a pretty case and a nice way to hang it on the wall like artwork. Here is a link to his vertical hopper http://www.thingiverse.com/thing:109650
