A modular cockpit panel for my Flight Instruments. The 100x100mm modules can be stacked vertically and horizontally as desired. Connection is done by M3x6 screws, M3 threads are included in the model on top and right side.

UPDATE 2023-01-08: Bottom module added
UPDATE 2023-01-24: Side walls added
UPDATE 2023-03-27: Back sides added
UPDATE 2023-08-31: Connector for extension modules added

Models are provided for standard 80mm instruments, with cutouts on bottom and a panel without any holes for customization. Bottom module provides a secure stand. 

Use the PCB Mount M3 for mounting an Arduino Mega 2560, glue them to the bottom modules as desired for your setup.

Side and back panels are now also available. Center panel rear cover has a cutout and a protruding cover for the attitude indicator.
