This is the Garmin GDU1500. This 3D printable project is designed to replicate the real Garmin GDU1500 for home flight sim users. The design is very open and can be used with X Plane, MSFS2020, FSX, P3D... It is designed to be panel mounted. 

The project comes with all the parts in stl format for 3D printing. It also has custom designed pcb Gerber files so that you can order the pcbs from a manufacturing service (the pcbs are also available for purchase in the FSDIY store) . I have also included illustrated instructions to help with assembly.
