Simple two-piece frame (without gluing)

Simple photo frame consisting of two parts that slide into each other. No need to glue anything. The attached model is created for 9x13cm photos, but in the attached scad file you can easily generate any size by entering the width and height of the photo into the prepared variables (Standard sizes are listed in the attached table). The frame has a hole at the top for a screw with a countersunk head for attachment to the wall.
