Slicer Settings:
In your slicer, ensure you use settings that suit the intended strength and finish of your container. A higher infill (around 20–30%) may be recommended for durability, and consider printing with a brim or raft for better adhesion.
Material:
Choose a filament that suits your use case. For a countertop item, PLA is common, but you might also consider PETG for increased durability.
