New payload bus
The new payload bus will be based on a multi-level tower design made from laser cut plastic disks and carbon rods used to support the structure.
Currently, the plan is to encase the frame in Styrofoam tortilla warmers, which will serve both as isolation at altitude as well as destructible landing padding.

Proposed miniature assembly:
The payload design depends on plastic planar structures to act as mount points for all payload components, as well as load-bearing points for the balloon and parachute.
To facilitate this design, Onno has designed a revolutionary new geometric shape which has been estimated to be between 100x and over 9000x stronger, lighter, and cooler than an ordinary disk of the same material and approximate size.
Balloon load bearing ring:
Standard mounting plate for cameras: Please note, this does not use the Onno ring, so it is the weakest part of the design, by approximately 900000%.
