This is my first console design for a Raspberry Pi case modeled after the Nintendo Wii. Just like the Wii, it has a door at the top to hide and access the USB and Ethernet ports.
To assemble the parts, you'll need four M3 screws that are 10-12mm long to attach the Pi mount and the USB port covers to the shell. You'll also need four M2.5 screws that are 5mm long below the head. This part is important since the tolerances on everything is a little tight. Speaking of tolerances as well it's important to print the door with little infill so it can flex in to place, if you're having trouble, try something like nylon or PETG instead.
This print is a bit more complex than my usual ones, and several parts need specific settings, these are the ones I've found that work the best.
Door: 1.mm layers, 2 perimeters, 5% infill, and 6 bottom and 9 top layers.
This is so it can flex in to place easily. PLA worked for me, but plastics like PETG, Nylong and ABS which have more tensile strength may be better.
Shell: .2mm layers, 3 perimeters, 10-15% infill and 8 bottom and 4 top layers. Use a 6mm brim as well to help it stay on the build plate.
Since screws are being driven in to serveral places where there's support material, more bottom layers help, as well as more perimeters. Aternately, the use of a M3 tap lets you get away with less solid layers.
How to place in the door correctly.
The door has two nubs and a negative spaces to accept them both. Start by placing one of the nubs on the door in to the shell while holding the door 90 degrees to the shell. I've found that it's easier if you place it in the negative space on the side that's thinner. Next, gently bend the door at the centre and swing the other nub in to place. There may be a bit of friction, but it will pop in. If you're experiencing troubles, don't force it, you can always scale the door down in one direction and reprint. If you're finding you're having a lot of issues with something like PLA, try PETG instead, it has more tensile strength and it's a bit more flexible , which is just about perfect for this!
