Printing Recommendations

The model has been tested and optimized for the following materials:

• PLA: Excellent for dimensional accuracy and rigidity. Recommended for occasional use.
• PETG: Ideal if you are looking for greater durability and resistance to temperature variations (useful if the key is stored in humid places or with significant heat exposure).

Suggested Settings:

• Infill: Minimum of 15% (Gyroid or Grid pattern) to ensure the shaft does not break when applying torque.
• Walls: 3 to 4 walls to reinforce the shaft structure.
• Layer Height: 0.2mm is sufficient.
• Orientation: It is recommended to print the key "flat" or with the shaft facing upwards with supports, depending on the desired mechanical strength in the rotation axis.

Safety Warning: This tool must be used strictly for emergency purposes. Keep it in an accessible location, but out of reach of children.
