This is an external box to house the USB, rotary encoder and AMOLED screen used by the Micro Gotek. Install the Micro Gotek inside the Amiga and pass the cables to the 3 mini boards through the openings on the Amiga and into this box. Mount them to the openings and you have access to all without cutting the Amiga or even seeing any wires.
Along with this, I also recommend printing a rotary encoder cap from https://www.thingiverse.com/thing:2832652 , it makes it much easier to user the rotary encoder.
This is a first version and there are a couple of issues. You need to bend the pins of the encoder, the screen and the USB to make everything fit, in the next version I will probably move the USB hole on the other side, where there is more space.
There is also currently no option for the buzzer which could just stay inside the box. I will add another hole for a switch for the buzzer, since I personally some times just can't stand it:)
