T-Notch adapter sub-part.

thingiverse

So I built an adapter for a friend to secure his programmer to a Sirius car mount. Later on, I purchased a Bracketron Vent Mount and noticed it had the same little T-Notch mount on it. I figure there are probably more T-Notch gadgets out there, so I'm releasing the T-Notch sub-part to integrate into your design. It comes in both .stl format and .123d for Autodesk 123D Design. NEW I added the matching T-slot that the T-notch connects to. Add it to your design. It's shown belly-up; attach the top side to the target, either recessed or not. (work in progress)
