Magnetic Breakable Vase
I created this with another prop master on a production of Blithe Spirit to have a breakable vase that could be reset every show. The pieces are held together with 3x6mm magnets that fit into holes on the edges. There are 11 pieces total (ascending from bottom to top), and I also posted the full vase model as well in case you want a second. Along with some pneumatic poppers, these helped create a really cool destructive ghost effect!
Thingiverse didn't like my demo video, so here's a video of me dropping it before painting:
