Ví thẻ Cascade card wallet V2 - Slim Remix

UPDATE 8/10/2025: strengthened wings

This is a reverse-engineered remix of popular “Cascade card wallet V2” by @Hugo. My version is slimmer (7.7 mm vs 11.5 mm), but fits only 3 cards. It also incorporates spring placement from @rycera3d_1916108's remix. 

Since it's not an edit of the original model, some differences may be present. However, functionally it's still the same.
