Michael Knobloch was so kind and generous to make his scratch built models available.
You can see the models of the moisture vaporator and the base used in his great diorama.
Follow the progress of his work in this thread (german forum): http://www.kartonbau.de/forum/star-wars-lars-homestaed-bauberichte-spezielle-interessen/board44-spezielle-interessen/t34743-f46/
The files are without instructions but with a little help from the images you can guess how they go together. If anyone makes instructions let me know 🙂
For the basement it’s a good idea to reinforce with strong cardboard to make it sturdy.
