You will need the following items for this print:
Follow the wiring diagram for soldering made by “madmon” on thingiverse.
According to madmon you do not need to connect PIN3 to VIN.
The external sync LED is not needed as the onboard LED's on the dev board will be used, print the insert in transparent filament to let the light from the LED's shine trough.
I recommend printing the insert in PETG or other heat resistant filament as it will be directly touching the ESP32.
To flash the dev board follow darthcloud's guide on Github https://github.com/darthcloud/BlueRetro
Follow point 1. on the wiki for this build.

I have printed and assembled several of these now and so far all of them have worked flawlessly.
I am a novice at 3d modeling and editing, if you have any questions feel free to leave a comment.
The author remixed this model.
Edited the space for the port hole in the bottom to accommodate the USB C port and edited the buttons because the original buttons would collide with the USB C port.
Included are also taller and flatter buttons than the original design since i prefer them to be more pronounced and I prefer the feel of the flat buttons.
