When I was a boy many years ago my parents had a coal bunker like this in the garden and then when I visited to Watercress Line recently they had one at Ropley Station and I thought I would design one incase anyone wanted to print it.
I have done two slightly different versions for this design, one has a base and the other doesn't.The design is approximately 12mm x 12mm x 13mm is OO scale (1/76)
Designed at OO Gauge, 1/76.2 Scale.for HO print at 87%, 1/87 Scale.for O UK print at 175%, 1/43.3 Scale.for O International print at 158%, 1/48 Scale.for N gauge print at 51.49%, 1/148 scale. (Caution: I have not printed this model in N gauge so can’t guarantee its printability)
The examples in the pictures were printed on an AnyCubic Proton M3 3D resin printer.I recommend printing these on a 3D resin printer to get the best print definition, It has been designed to also be printed on a FDM printer using a 0.2mm nozzle (Detail will not be as good as a resin printer). As normal with my designs, there is a balance between accuracy and printability, hopefully not affecting the look of the model too much.
I use AnyCubic Water Washable Resin for most of my items but use AnyCubic ABS Like Resin for anything that needs to be stronger and tougher.
