Anti-loss cover for Sony A6400 Smallrig cage wrench

Designing an anti-loss cover for the magnetic dual-head wrench on SmallRig camera cages.

Currently tested and verified on models A6100, A6300, A6400 (tested in person), A6500, and A6700.

Based on SmallRig's official website design,

many cages featuring built-in Arca-Swiss quick-release plates

such as those for the A7 series, A7C/R, and FX3—also share this bottom structure.

Therefore, it appears this design is widely compatible across these models cage have arca swiss as well.
