Originally made for a friends castle dollhouse. There are two window frames - exterior weathered stone and interior wood.
Both frames are designed around a window opening of 2"w x 3 1/8" h, but can be scaled to fit whatever you need.
I do recommend printing the wood frame at higher resolution (<1.0) for more details even though I mass printed mine at 1.0 (came out fine, but had to print 30+ of them, time saver).
No supports needed, just used a skirt. Pretty difficult to get a failed print.
