I found increasing the floor and ceiling to 4 layers made for a cleaner look, but your print setting might vary for this depending on you printer. No supports were required, but if your slicer supports adding custom supports, it may not be a bad idea to add a couple thin supports to the port hols on the CPU box. Though I did not find this necessary, some printers do not do bridging well.

I wanted to make this as simple to assemble as possible. No screws are needed. You will need to glue the CPU box to the backer-board (this was sperated to prevent the need for supports in the print process). Everything else clips together. To keep the LCD in the proper location, you will need 4, .75cmX .75cm foam or felt cubes (I used a small stack of felt feet). You will also need 4 more felt squares that are .25cm thick (1 thickness felt foot pads)
1) Glue the CPU box to the Backer-Board. You will need to set it into place point first from the ribbon channel as it is recessed.
2) Assemble the LCD and Raspberry Pi. This box is designed to hold them when configured using the classic assembly method, and will not work if you invert the board for a low profile design.
3) Place the .75 felt cubes onto the marked indentations on the inside of the backer-board.
4) Place the assembled LCD/Raspberry Pi into the newly assembled back
5) Place the thinner felt pads on the inside of the bezel in each corner on the sides (see pictures)
6) Lower the Bezel over the LCD. This should only fit in 1 direction.
7) Slide the entire unit into the stand base. This will act as the "clip" that will hold the lower part of the housing together
8) Place the Top-Clip onto the top of the unit. It should fit in such a way to allow for access to the camera mount slot.
Note: If you are going to be installing the camera, you will need to first install the ribbon cable onto the Pi and feed it though the slot in the back of the CPU Box. You will not have access to this port to make the connection from the outside.
