I uploaded this as an example of this great software I found on Pinshape by masih akbari.

You can convert any photo or image into a 3d printable relief, whether it's a photo of your loved ones or your favourite poster, this program works beautifully! models can be scaled down easily to make personal pendants or keychains as well. I included a picture of  a pendant I made of myself and my Gf as an example. (35mm x 50mm)  

(the pla I used for this print was old glow in the dark, which was dry and brittle. it allowed some paint seepage. for best results always use fresh, pliable filament)
