Also built mine. 1/4" clear acrylic with a hinged full length front door and removable rods/hangers for 4x5 sheet or 120 roll film. The cabinet is sized to be just big enough to accommodate only 4x5 or 120 film to save space (it's not tall enough for 35mm, but then I very rarely do 35mm anymore). I'm also using a twelve volt computer fan to pull air out at the top; high quality air filter at the bottom to keep dust from being pulled in. The little white tray is a Paterson 5x7 to collect drips. Film dries without heat in four hours or so.
