Model Railway Brick Coal Bunker - Resin and FDM Tested 3D print model

Many years ago these were commonplace when people heated their houses and other properties with coal. On railways signal boxes and other railway buildings were also heated by coal but they needed somewhere to store coal and that's why coal bunkers were built to store the coal until needed.

I have created two designs, one with a base and one without.

This item has been designed at OO gauge, 1/76.2 scale. For HO Gauge print at 87%, 1/87 Scale, For O Gauge UK print at 175%, 1/43.5 scale, For O Gauge International print at 158%, 1/48 scale, For TT Gauge print at 63.5%, 1/120 scale, for N Gauge UK print at 51.5%, 1/148 Scale, (Caution: I have not test printed this in N gauge scale).

The examples in the pictures were printed on an AnyCubic Proton M3 3D resin printer. I have also now tested on a Bambu Lab A1 printer and it prints fine, a model with base needs the FDM stl file. I recommend printing these on a 3D resin printer to get the best print definition. As per normal with my designs, there is a balance between accuracy and printability, hopefully not affecting the look of the model too much.

I recommend 3DLAC Spray to help secure the print to the print bed whilst printing (FDM), it also helps release the print after printing has finished. https://amzn.to/4cxPybm (Amazon)

The main resins I use for printing can be found with my affiliated links below. 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.
