Use This keychain can be used to hold keys or as a decorative accessory, adding a stylish touch to backpacks, bags, or key rings. Printing Suggestions For best results, print with a filament that offers a contrast in color, such as metallic or bright hues for the lightning, using a layer height of 0.1 to 0.2 mm. Supports may not be necessary. Assembly Instructions After printing, attach a small keyring through the top loop of the cloud to complete your keychain.
