Medium window for boneworks

A medium sized window which I created for a model building on my 16mm:1ft scale railway. The window was designed to be 54mm x 77mm x 4mm with six panes. I have made the frame 4mm thick which should hopefully mean that if you scale it down for a smaller scale, it should still be viable. This object was made in Tinkercad.
