Vault MkII (Combination Lock)

This is a thoroughly re-engineered version of the original "Vault with Combination Lock", redesigned to be fully compatible with compact 3D printers like the Bambu Lab A1 Mini.Key improvements and differences include:✅ A1 Mini compatibility: Simply scaling the parts wasn’t enough, as some lost their functionality. Many components were redesigned with a custom scale.🔁 The rotating lever for opening and closing has been removed — the mechanism is now automatic, triggered by the motion of the combination input shaft.⚙️ The number of gears has been reduced, making the visual aspect slightly simpler.🧩 The door no longer requires glue — all parts can now be fully assembled using bolts.🧷 A ball bearing has been added at the base of the camshaft for smoother operation.🪗 A spring has been integrated to keep the combination mechanism discs tightly pressed together.🔢 The combination discs were redesigned as multipart pieces, allowing users to set custom combination numbers.📐 All tol
