We already build the first version, shown at Expo HispaLUG 2019 in Granollers.

Afterwards we tried the second version, but it has indeed problems with the 90° curves. So it was never presented from ourselves.

Now we are rebuilding the suspended version. The functional prototype works, also the cladding we achieved. Now the prototype of the other compartments are under development.
