OO gauge windows 3 versions 19.5mm x 16mm x 5mm

thingiverse

This are the first 3 windows I will be adding. They need to be resin printed and the opening size is 19.5mm x 16mm and the depth of the window is 5 mm. My wall tend to be 3 mm thick to represent a 9 inch course.These models are very delicate and I remove the supports before curing them in cod water ad I use water washer able resin. Its a trade of with scale and printability.
