A Dome built from PVC elektro installation pipes.
The connectors are made from 4mm Polypropylene, that was lazzzorcut.
Conclusio: Buildup is super fast, structure is stable enough to cover, but not stable enough to lean on to.
Some of the connectors broke during teardown.
We should make the connectors out of steel.
The pipe lengths are the following:
- green: 119 cm
- yellow: 141 cm
- red: 144 cm
According to  it therefor has a diameter of about 7 meters.
