This is a door and window frame I created for a petrol station I'm building for my 7mm/ft or 1/43 scale O gauge model railway.
I made it to the specific size I needed so the approximate dimensions of the aperture it fits are:
Overall width 57mmOverall height 45mm
Height of window section 35mmWidth of window section 34.25mmWidth of door section 22.75mm
I have made the design slotted at the top so you can slide in the glazing. I use acetate sheets cut down to size.
I print the frame lying back directly on the build plate. It is designed so that there is no elephant's foot effect on my printer. I have also included a version of the file with the door frame supported with some mini supports on the inside.
I also have some other windows available that I created for the same building. You can find them here: https://www.cgtrader.com/3d-print-models/hobby-diy/other/window-frames-for-7mm-scale-o-gauge-model-railway-building
I sliced the file in Lychee and printed on my Anycubic Photon Mono X using Siraya Tech fast resin.
