Cat Skeleton Keychain Lithophane

A flat cat-shaped charm that hides a skeleton in the light. The model is a slim, solid cat silhouette — a lounging cat outline with a rounded head, ears, curled body and tail — pierced with a small loop at the top so it threads straight onto a keyring or zip pull. At heart it is a lithophane: the cat's body carries a varying-thickness relief of a feline skeleton that stays subtle in the hand and only reveals itself when you hold it up to a lamp or phone torch, the bones showing through as bright-and-shadow. It makes a great little gift for cat lovers, spooky-cute and Halloween fans, vet-clinic goodie bags, or a stocking filler and swap-meet freebie. It works equally well as a bag charm, keyring, or a small hanging ornament. Print notes • Print flat on the bed, lithophane face up, at a fine layer height (0.08–0.12mm) so the skeleton gradients read clearly. • Use white or a light translucent filament and 100% infill so light passes evenly — thin areas glow, thick areas stay dark. • No supports needed; the loop prints in-plane with the body. • Slow the first few layers for a clean, gap-free flat face — any gaps show up as bright spots when back-lit.
