My daughter wanted to do a 3D printed Valentine's Day for her classmates this year. We chose this simple necklace that holds a Hershey's Kiss. They can enjoy a single kiss or keep it reserve for a chocolate emergency.
I printed these on a Rep2 at Standard (Layer .20mm), the top and bottom snapped together well. Depending on the print seam, connecting them could be a touch finicky.
To take it apart, its best to squeeze the top piece at its fattest point just above the bottom piece.
I have included bottoms with a smiley, a first aid cross, an "emergency" exclamation mark, and plain.
Just add your own string through the holes at the top to make for a quick and easy little gift. Hope you enjoy them!
