4x5 Combiplan

Added a tank. Not sure if possible to make watertight. Maybe make a seal of soft TPU or a strip of silicone. Have not measured amount of liquid needed, but probably around 1 liter.

Everything should be acetone smoothed to waterproof it.

Version 1 of a 3D printable 4x5 combiplan. Some parts need glue. I printed mine in ABS and use ABS/acetone "glue". The jagged film retainer labeled "TPU", should not be glued. It's supposed to be a snug fit to retain the film. Idea was to print in TPU, but it is not necessary.
