Airplane Keychain
This airplane keychain is a simple, modern, and scalable design that prints perfectly without supports. It includes a keyring-ready hole and works great in any size—small, medium, or large. Ideal for gifting, everyday carry, or adding to your keychain collection. Designed for smooth print results on any 3D printer.
Print this model flat on the bed for best results. Use 0.2 mm layer height, 15–20% infill, and 2–3 perimeters for strong walls. No supports are needed. PLA is recommended for quick prints, while PETG gives better durability if you want a tougher keychain.
