dental retainer case 3d model

3D printable dental retainer case, round pebble-shaped organic compact container. Functional mechanical design split into two halves: bottom base and top lid, connected by a flat 90-degree opening mechanical stop hinge on the rear. The exterior form is circular from the top view, with smoothly domed, filleted, rounded edges curving towards the center. Designed for 3D printing flat: both the top lid and bottom base lay completely flat at 180 degrees open on the print bed with zero overhangs or supports needed. Interior features: - Hollowed smooth internal cavity tailored for orthodontic clear retainers. - Cylindrical magnet pocket recessed on the front lip of the top lid: exactly 6.2mm diameter by 3.2mm depth (for a 6x3mm neodymium magnet). - Matching coaxial cylindrical magnet pocket recessed on the front lip of the bottom base: exactly 6.2mm diameter by 3.2mm depth. Clean manifold topology, watertight mesh, functional CAD-style tolerances, smooth surfaces, ready for FDM 3D printing.
