Printing Tips

   Print Settings:
       Layer Height: Set the layer height to 0.2 mm for a good compromise between quality and print time.
       Filling: Use a filling of 10-20% max to ensure buoyancy while maintaining the solidity of the model.
       Material: Use PLA or PETG, lightweight and buoyant materials, suitable for humid environments.

   Supports:
       Use of Supports: Activate the supports for the overhanging parts, particularly under the fixing ring to guarantee a good result.
       Media Density: Set the media density to approximately 15% for a balance between ease of removal and stability during printing.

   Adhesion to the Plateau:
       Brim or Raft: Use a brim or raft to improve adhesion to the bed and prevent warping during printing.

   Print Speed:
       Setting: Print at a moderate speed to ensure good surface quality and avoid defects.

   Temperature Settings:
       Extrusion Temperature: Set the extrusion temperature according to the filament manufacturer's recommendations (generally between 200-220°C for PLA, 220-250°C for PETG or indicated on filament spool).
       Platen Temperature: Set the platen temperature between 50-60°C for PLA, and 70-80°C for PETG.

Post treatment

   Removal of Supports:
       Carefully remove the supports using wire cutters or a craft knife, then sand any rough areas to a smooth finish.

   Waterproofing:
       To improve waterproofing and durability, apply a coat of varnish or epoxy resin to the entire surface of the key ring.

   Buoyancy:
       Check buoyancy by placing the keychain in water before use. Adjust wall thickness or filling if necessary.

Personalization

   Bright colors :
       Use brightly colored filaments (yellow, orange, red) for better visibility in the water.

   Writing space:
       If not already included, create a flat surface on the buoy where you can write or engrave personal information (name, phone number).
