Cute little quick print designed to hold a Hershey's Kiss. Use it as a pendant, charm, keychain..etc
Once snapped together to get them back apart I've just squeezed the top half a little and then used my fingernail to catch the edge to pop open. If really stubborn a small tool of some kind can be placed through the heart to pop them open.
The top half may need a small brim depending on which build plate and/or if you are printing multiples.
Majority of filaments I used (PLA) resulted in the top and bottom being able to click nicely together. I did have one filament where they were a little loose. Adjust X and Y on the bottom section if you need to tighten them up. I did do one test in TPU but they wouldn't stay together but I'm not very experienced in it.
