hidden skeleton keychain

My wife is an x-ray technician, and asked me for funny keychain. I took model of skeleton cookie cutter, and used in tinkercad, to create keychain where skeleton is visible under light. Photos are taken from bigger version with thinner walls which has more contrast. Propably it could be a good halloween or christmass tree decoration.

On pictures there is model printed using fluorescent PLA with layer 0.12
