Build Your Own
Every Void dome is open-source hardware, licensed under CERN-OHL-P-2.0. All three variants share the same 3D-printed shell — they differ only in electronics. Pick your level and start building.

No electronics. Print and grow.
The simplest build — just 3D-printed parts and a substrate block. No wiring, no firmware, no soldering. Perfect for beginners.
