Onshape Dogbones and Corner Overcut

I've been playing around with Onshape and it seems pretty powerful while allowing free usage for smaller users. But a lot of my parts need to be cut out on a CNC router. And it is annoying to have to carve out the corner overcuts and dogbones by hand. So I added a couple of custom features.

To use them, you can view or clone my public document here:
