Trunk Cargo Hook

Clip-on cargo hook for the rear load-area rail, physically shown installed and documented by the creator as used reliably for more than a year. The creator directly lists X3 E83, 3 Series E46, X5 E53 and 5 Series E39 compatibility, so all four live generations are linked. This is an accessory rather than a reproduction of a BMW service part. Print in PETG as documented, observe sensible load limits, and confirm it cannot obstruct the rear seat or cargo cover.
