I wasn't happy with what was available commercially for 4mm guttering so I decided to 3D print my own. I decided on Ogee guttering for the goods shed and at first I designed the guttering on its own with the support brackets attached and no trough. The trough was then milled out on my milling machine to give a more realistic look to the gutter. The end result wasn't too bad but a very tricky operation and time consuming. The reason I did this was because I thought my 3D printer would not be able to handle the thin sides and they would need support when printing. With a leap of faith I decided to push the printer to its limit and print a gutter with the trough, support brackets and this time with the facia attached. Printing at 0.01mm layer thickness with no supports proved to be a success and with the washable resin, cleaning the 3D print was made easier. If my build plate was bigger I could have printed out the correct lenght for the goods shed but instead it had to be printed out in two lenghs which will be joined when attached to the goods shed.
