GMA-1347 AUDIO PANEL
This page is split into three main sections:
Parts Guide
Print Guide
Build Guide
The ultimate printer I can recommend is the Bambu Labs X1 carbon with AMS or P1P if you have deep pockets. ($1200). It's a massive leap forward in 3D printing, with excellent quality and impressive speeds. It's pretty much press print and go as the software and hardware do the calibration before each print.
This design is part of the Garmin G1000 setup for the Cessna in MSFS 2020. It's fully operational with each indicating arrow illuminated by a 3mm led. The button backlighting is handed by led tactile switches.
Cleverly split into two sections to make printing simpler and quicker. The design will fit a standard print bed of 220 x 220mm.

Place the faceplate (1) over the top of the buttons. There are currently 3 versions of the faceplate. You only need to print one version that suits your needs. 1A is blank, 1B is engraved text and 1C is embossed text. The embossed text can be filled in with a paint pen (white) or printed in white PLA/resin. Spray the faceplate black, then sand the raised surfaces. This will reveal the white embossed details.

To secure the unit to your instrument panel, use the mounts (6) at the back of your panel. There are two 4mm screw holes in the unit to attach the panel. These mounts allow for a hole to be cut out, and the mounts are used to help attach the panel. For a 3mm panel, M4 x 20mm screws should be used. Thicker panels would require longer screws.
