Roman Mile Fort - Hadrian's Wall 1/100th scale

I decided to make a model of a Roman Mile fort on Hadrian's wall in 1/100th scale for my 15mm miniatures. The model features a guard rail similar to one I saw someone else make that seemed like a good idea. Having an open side seemed dangerous but who knows if it was accurate or not. The files include angled corners for smaller printer beds as well as L shapes for larger printers.
