Here are the parts for my series of 2" to 3.5" lightweight, high performance frames.

Features:
Low drag design
Lightweight
Props out of view (when camera angle is >around 20 degrees).
Unique zero screw FC mounting for great durability and vibration rejection.
Can carry a vista or naked vista (which is well protected without needed to drill the holes in the vista out).
You can swap the entire stack and motors between different frames with 12 screws and no soldering. If you leave some slack in the motor wires your can easily try different size frames.

Example build: https://rotorbuilds.com/build/28832

The TPU parts for this frame are attached. Print 4x of the vista mount (flat on the bed with supports) and vista spacers. I use nylon m2 screws to attach the vista to the mount and titanium m2 screws for the motors, and attaching the TPU parts to the frame.
