need a scad expert

I have a python script that generates an SCAD the attachment is the out is an example of a simple file it creates. the edges on top of the file are square, i need them beveled to be sharper. I can either have the job be the modification of the SCAD file so i know how to modify it on the other files i made, or to modify the script itself (i would prefer to just have the SCAD file modified to what I needed so i know what to change). the attachment is what i want the edge to look like (more or less) I am not sure about price!
