🛠️ Recommended Printing Details

• Detail Quality: The worn stone texture of the wall excellently conceals layer lines (IMG_8503_3.jpg). A layer height of 0.16mm or 0.20mm will provide an optimal finish.
• Water Safety: If you are going to submerge it in an aquarium with living beings, it is recommended to print in PETG or use a food-grade and aquarium-safe epoxy resin coating/varnish to ensure it is 100% safe for your fish.
