• I recommend using ASA, and if that's not available to you, then use PETG. You can use my PETG print profile to print ASA (or PLA) - just change the material in the app when you print.
• You can use PLA but they won't last as long in direct sunlight. If you are going to use PLA, consider using black as the “carbon black” dye absorbs some of the UV.
• Make a test print first. If your wires are too thick, increase the scale as necessary (someone mentioned 105% worked for them, your scaling may need to be higher). And upload your scaled print profile with the model/brand/details for others!
• Get gauge 6 or smaller screws.
