Remixed from AndrewBougie's Mini SNES for Pi 2/3. I opted to go with the Pi Zero since they are only $5 at Microcenter and also to close off the openings on the sides for the USB ports and SD card. I also got rid of the mock controller ports and added openings for USB ports for more authenticity. Future improvements I need to make are to the rear ports for the power and HDMI.

Bill of Materials:
-Case: Top and Bottom
-Eject button
-2x power/reset buttons
-Raspberry Pi Zero
-Micro SD card
-Mini HDMI to HDMI adapter, (remove the outer plastic shell with a hobby knife)
-Micro USB Power Supply
-USB hubman - take off the plastic bezels, cut off the male end and solder the 4 wires to the Pi Zero shown here:

-Controllers of your choice
-4x 25 mm or longer M2 screws, I couldn't find anything longer than 25 mm locally
-Standoff STL files are optional, glue them to the top part of the case if you can't find screws longer than 25 mm

Surface finishing:
Sandpaper
Filler putty/primer for smoother finish
Light grey, dark grey, and purple paint (acrylic or spray paint)

I also used a hot glue gun to keep the ports in place and glued the board of the hub below the Pi Zero and covered it in a layer of glue to prevent a short circuit.
