Hawkeye Firefly Flat Mount TPU (For angled drone cam base plate)

had an idea to make a flat mount for the firefly micro. hope you like it enough to give me some pointers. my very first fusion 360 design. never done this before.
V2 is usable with PLA.
V3 has some slack, if you like to use paper or cotton to dampen mic, place on opposite side of opening.
V4 was made to be a tight fit. Hopefully, the tolerances wont allow it to move around.
Any input is greatly appreciated.
