I have created a couple of industrial style interior doors for use on my 7mm/ft or 1/43 scale O gauge model railway layout.
They are designed to be printed flat on the build plate, and are thin enough that they can be glued directly onto the interior wall of your building if you don't want the bother of cutting out the door openings.
Dimensions including door frame are:H 49mmW 23mmD 1.4mm
I sliced the file in Lychee and printed on my Anycubic Photon Mono X using Siraya Tech fast resin.
