Here's my spin on your request: Modified to work with the M10 Push fittings. Larger drive gear required (12mm in diameter) Support plate is designed for dual assembly - it's a work-in-progress, so feel free to experiment and get the motors close to the aluminum frame, letting them act as heat sinks.

If you opt for PLA like me, and your motors reach temperatures above 50°C, you'll notice a slight bending issue - simply reprinting should resolve the problem. On the matter of support points, I'm still skeptical about using just one point to hold up the 608 bearing; it seems rather weak to me. Perhaps Airtripper's design would offer more stability.
