Egg Drop Challenge Winner

As we had a challenge at the university, I designed and printed out this cartridge in a tube.
We won :)

To find out how it works exactly, please read in the section "How I designed this" below.

The Shpere and the Main Body should be printed with the thread at the bottom.
The 2 Inner parts (cartridge) with the thread at the top.

Print the Bumper with Filaflex or another flexible material and with no bottom layers, a low infill (cube-pattern) and one perimeter.
