desiccant with thicker walls for hygrometer

Not bad at all - I really do like this model, but in the end I decided to print one of the more traditional designs (under the spool) instead. I'm worried this leaks slightly, and it's a bit of a pain with the (necessary) supports. One thing you might think about doing is designing it so the square hygrometer holder can be printed as a separate part that just friction fits into the dessicant jar. That would really reduce the number of supports.
