I'm looking to propose to my girlfriend using a 3D print of a ring pop. The engagement ring will be inside the ring pop; revealed by removing/opening the top. I've found various models online, but none have quite fit my needs. I do have 2 models currently, one .dxf and one .stl. Both of which are solid top pieces. I need to hollow out the top gem/candy portion and make the top part removable to reveal the ring. I have no experience with modeling, but I feel like it'd be quite simple for most of you. Let me know if you're interested in helping. Thanks!
