I am a little concerned about the heat resistance of the PLA. Temps can get quite high in full sun. I think a high temp PLA or an alternate type of plastic would be more warp resistant. I had a 3D-print quad in a car for a day and the arms were totally deformed after.
The efficiency is not great as the water in the smaller collection bottle also evaporates, condenses and returns. Not sure how to shade that...
Using a damp cloth wrapped on the top section creates shade and evaporative cooling to occur, boosting the condensation rate.

Now sized correctly, the bottle halves fit into the thingy instead of around. Should be lots more stable. Now I have to wait for some sun to test... may be a while!
Still looking for help with customization scripts!!

Redesign with a top and bottom collar going outside bottle. I think this is the ticket...
Will print in the morning!

I am trying to size this thing for North American 2L straight-walled pop bottles. After many iterations and sizing changes I finally found the size that works, with the bottom of the thing slipping over the cut bottle bottom and the top fitting inside the bottle top. The inside fit doesn't seem the way to go, so I plan to change the top of the thing to match the bottom with an inside fit.
It is getting bigger... not what I had in mind initially, but I guess we have to go with what works.

I would like to make this project customizable to fit different diameter bottles. I need help creating a SCAD file, or something else that would work in the thingiverse customizer (or outside stand-alone for that matter). I am really not sure how this stuff works.
The end goal here is to make this thing universally adaptable for all parts of the world. Combined with a #PET Bottle Recycling 3D Printer, many of these could be manufactured where they are needed the most.
So if you care about this project enough to contribute, please let me know!
