Wall mounted chicken and chick waterers using PET bottle

Two waterers which use a PEG bottle. The smaller one is suitable for chicks and bantams, the bigger one is for adult chickens.

Print vertically and use 4+ perimeters to make the print watertight. 

The bigger waterer can be used with both stands, if using the simpler smaller one, the bottle has to be supported at the top using a wire.

The chick waterer is used with the smaller stand, and doesn't need to be supported if used with a smaller (0,5 l) bottle.
