Halls Greenhouse Drainpipe Adapter

thingiverse

There are various different sizes and shapes of Halls Greenhouse guttering. This design fits the one I have — I've no idea what model it is as it was there when we bought the house. It attaches to a standard UK garden hosepipe with a nominal ½ inch internal diameter. This is best printed with the part which is usually horizontal pointing up, and the pipe adaptor part horizontal on the print bed. (It's the way the STL files are oriented). I printed it with 0.16 mm layers and no support.
