Don't be too proud of this technological terror you've constructed. The ability to destroy a planet is insignificant next to the power of the Force.
Over on the replica props forum, the geeky prop identification wizards have figured out at least half of what makes up the Death Star's coffee mugs in the first Star Wars film from 1977 - a Tupperware Jel-ette gelatin mold. But the top portion hasn't been identified yet. Which means if I wanted a replica I'd need to figure out something for the other half.
I got my hands on some of the Jel-ette molds - so I took the time to replicate those as well. The molds here are dimensionally accurate on the external dimensions. Everything is optimized for FDM printing.
The author marked this model as their own original creation.
