20mm t-slot 90 degree joint

I'm upgrading my Prusa2 to a Mendelmax, and I didn't want to drill holes in the T-slot at the top (at university, no access to decent tools). I saw a 90-degree joint on Thingiverse (the one listed as a parent thing), but I wanted to make some improvements. Built-in support - with such a simple part, I prefer designing it in, then printing without support in the slicer. I find this uses less plastic and is easier to remove. The ridge that sits in the T-slot is continuous between the two rods - it guarantees perfect alignment. I threw together a SCAD file quickly, but it's not parametric at all - just something to get me started.
