Model Railway Small Coal Bunker

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 in case 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) These items have been designed at 1/76 scale but can be printed at other scales.Primarily, these items have been designed to be printed on an FDM printer, but can also be printed on a Resin Printer.designed at OO gauge, 1/76.2 scale.for HO gauge print at 87%, 1/87 Scale,for TT120 gauge print at 63.5% 1/120 Scale,for O gauge UK at 175%, 1/43.5 Scale,for O gauge 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
