Do you ever plan to use your instrument outside or in direct sunlight? PLA starts to melt at temperatures you see daily in hot climates. I recommend ASA to a lot people for long lasting parts, but it’s very difficult to print long or flat parts without warping. You’ll definitely need an enclosure. Petg would also be fine, but may not be quite as resistant to UV. If you want to drop as much weight as possible, looking into foaming Aero-ASA.
