Mirrored splitting diagonally and adding holes for inserts

Hi guys, i'm really struggling with this one and even lots of research didn't clear up how i should approach this.
I've designed a tablet case that i plan to 3D-Print, unfortunately the Print-Bed is ever so slightly too small. Therefore i need to split the case diagonally and print it in two parts. This split needs to be at an exact position in the frame to leave enough room for the threaded inserts that i want to use to screw them together after printing.
I believe this should work, but i don't know how to position two planes to split with mirrored through the center and how to split using multiple planes at the same time.

Maybe this image explains the situation better. Notice the drawings in the left and right corners. (Case in green, Ignore the already existing holes, they are for threaded inserts to attach the back that i will model later).
Any help is greatly appreciated!

Yes there is. I think my suggestion above is much more sraight formard. just drawing a line in the same way you suggest in your workaround. Attach a plane to the line. Then use the split feature selecting the pane as the tool and the part will be completly split where the plane intersects the part. You will not loose any geometry this way either. If you need the split to be in the shape of a drawn profile then you would extrude a surface and use the surface as the tool for the split feature.

Can you draw a line along the path you want the plane to sit and then hook the plane up to the line? Or use the line/lines to extrude a surface and then use the surface as the splitting tool?
Hi Shawn
This could be a possible solution. In the meantime, i found a workaround: Create a Sketch on the topmost surface, draw lines over the geometry you want to cut, and the inner ends of the lines together and the outer ends together with more lines. Then Thin-Extrude a very thin ribbon to cover the entire cross-section to split. Then split using that ribbon.
But there has to be a more straight forward way, right?

Thats Brilliant. Thanks for the short video, very useful. Not something I've needed to do before but now know how to if i need to!
I guess I'm totally missing what exactly your trying to do. 😁
Oh i see now. Thanks for the video, this helps alot!
