Update (4/4/18) - Updated the top case due to the 3.2" TFT screen catching on part of the of case near the top right corner. This issue should be fixed with the new uploaded file.
Update (1/16/18) - I will be doing some new video tutorials on how to build this project from start to finish including a live stream on YouTube of a full build from start to finish. Please make sure you follow my accounts to keep up-to-date!

Update (8/27/17) - It's finally here! A working image file of Retropie 4.2 working properly with the Pi Zero W enabling onboard wifi and bluetooth! This image has been setup for the 3.2" PiTFT (although it will work with others) and enabling the I2S amplifier for proper audio from your Pi. I've also added a new theme that works much nicer with smaller screens, which will be easier to see the menus. Please let me know if you have any questions, but if you plan to make any PiGRRL Zero (Plus or non-Plus), this is the only image file you'll need!

The PiGRRL Zero, but with a much larger screen!
This is the remix of the original PiGRRL Zero and a variation of the PiGRRL Zero that I recently designed to include an amplifier, external speaker, and standoffs to hold the case together (http://www.thingiverse.com/thing:1621907).
This remix of PiGRRL Zero modifies the case size horizontally approximately 0.5" to accommodate a much larger screen. The screen has been upgraded from 2.2" to 3.2" utilizing the 3.2" PiTFT screen from Adafruit (https://www.adafruit.com/products/2616) and wide face tactical buttons for the PiTFT (https://www.adafruit.com/products/1489)
This design still runs off the Pi Zero which is attached to the back of the PiTFT, just like the original build. You will have to do some modification to the PiTFT and the Pi Zero to make this configuration work, including directly attaching the wires from the PCB's to the Pi Zero GPIO ports. I have several tutorial YouTube videos showing how to complete this build, including some tips and suggestions, so please refer to those in the links attached below.
You'll also need to rotate the screen because it defaults differently than I have it in the case. Go ahead and use linux commands to modified /boot/config.txt and at the very end add "display_rotate=2". Here is a link to a forum article that explains how to do this. - https://www.raspberrypi.org/forums/viewtopic.php?f=78&t=110948

If you want me to print you a case, go ahead and hit me up on my Etsy shop. I have this setup and tuned to print very nice versions of this case. If you have a certain color you want, just submit an order and I'll pick up some filament. If you want me to build one of these from scratch for you, hit me up on my Etsy shop. I have a listing that you can purchase one, and I'll assemble it with the color you want.
