This is a heart pendant that will accept inserts. The picture shows and insert in place which would be printed in white strong & flexible material, or whatever color you like. The insert should be able to snap in and out so you can change it as you like. I have not made on myself yet so I can not be sure that it will snap in and out as desired. I will design a couple of other variatons on the snap in insert and print them all to see which design works the best. Keep watching this space for updates.
