Model Railway Station Concrete Panel Fence

I have been meaning to do this design for some time, but after a recent visit to the railways in the South East (England), I saw this fence at many of the stations I visited. These fences are commonly used on the back of platforms or around railway station locations. I have designed this model with various length sections, with a 21mm distance between posts and a 20mm-high fence. I have four section lengths: 43mm, 85mm, 169mm and 253mm, and these have a post at both ends. I have also done the same lengths, but one end doesn't have a post, so it can be slotted into the other sections; these are labelled with ext at the end. This item has been designed at OO gauge, 1/76 scale.for HO gauge print at 87%, 1/87 scale,for O gauge UK print at 175%, 1/43.5 scale,for O gauge American print at 158%, 1/48 scale,for N Gauge UK print at 51.5%, 1/148 Scale (Caution: I have not test printed this in N gauge scale). These items have been tested on a Bambu Labs 1 Mini. Additional Info Please check my Web
