Print Settings & Material

• Material: PLA (Successfully tested and printed).
  • Note: While PLA works great for fitment and standard use, consider PETG or ASA if your radiators reach exceptionally high temperatures to ensure long-term durability.
• Infill: 20% (Gyroid or Grid) for good structural strength.
• Wall Loops: 3 for extra durability around the internal socket.

• Supports: Not strictly necessary, but a small amount of support inside the top cavity can improve the finish of the internal "ceiling."
