MagSafe Puck Holder Duo (Repaired)

Repair the failed part magsafe_puck_holder_duo without redesigning the entire charging station. The OpenSCAD module part_magsafe_puck_holder_duo() currently produces empty geometry. Rebuild it as a valid, watertight, printable solid using a positive outer cylindrical body and a recessed circular pocket for the official Apple MagSafe puck. Use a 3 mm minimum wall thickness and a 3 mm backplate. The puck recess must be shallower than the total holder thickness so the subtraction cannot remove the entire body. Add a small cable exit notch. Use valid positive dimensions and ensure all Boolean operations preserve printable material. Keep the puck holder separate from the support arm. Preserve the existing mounting interface where possible. Render and validate this individual part before attempting the full assembly. Confirm that the module produces nonzero-volume geometry and exports successfully to STL. Do not change other components unless necessary to resolve this specific failure.

Parameters

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
