I designed this for my Philips VG2835 MSX2 computer, and then made it configurable for more situations.
It uses a 3.5 inch mounting frame with a configurable front panel.
Height, width, vertical shift and interface locations can be selected as well as the original 7-segment display or a 0.91 inch OLED.
The included .STL file is only an example (in this case for the aforementioned MSX-2 computer)
A second LED is optional, as is a rotary switch.
when a rotary switch is selected, the up/down switches disappear and a new location for the activity LED(s) is implemented. It is assumed that the user removes the switches from the PCB and rewires the LED(s).

I designed it to be printed with a 0.28mm layerheight and 0.4mm nozzle
