Split a body/union to print as two pieces

I am making a small window screen and have drawn what the full size screen will be but I need to split the body on the line shown. I can extrude everything off of one side, export and import the pieces but I’m wondering if there is an easier way. There is a corresponding piece that will complete the sandwich with the screen in the middle.


Make a construction plane on that line and use the split body tool. You might consider a diagonal cut for more glue area. You can rotate the plane to achieve that.
