Swiss army keychain with space for nfc

thingiverse

This is another Swiss army keychain that I designed to accommodate a single NFC key. Details: * Space for one NFC key, featuring an exposed hole to view it. * A textured surface of circles enhances grip and visual appeal. * An adapter for attaching a keyring allows extra or temporary keys to be stored, or the keychain itself can be secured with this attachment. * The NFC adapter is designed as a separate component to avoid any potential supports, which may also be printed in a contrasting color and then glued into place. * Three distinct upper part designs are available: * A version without an NFC key compartment * A design featuring a wireless icon-shaped hole * A Zaragoza Maker space logo-shaped hole is also an option * The positioning of the indentation determines whether the bottom part needs to be mirrored for proper alignment. * Additional support can be achieved by incorporating washers and/or springs to securely hold the keys in place. * Warning: some clearance between the NFC key and other attached keys is necessary for optimal performance, as moving the keys out of the keychain may be required if this gap does not exist. * The nuts and bolts used are M3 (DIN912 and DIN934), with a recommended purchase option available through Amazon.
