Sliding-Lid Enclosure

Create a functional two-piece 3D-printable enclosure for a device called Quick Lens. Required internal clear space: * Length: 46.4 mm * Width: 34.9 mm * Height: 22.2 mm The enclosure must have: * One lower rectangular body * One thin sliding top lid * No holes, openings, logos, screws, glue, magnets, or internal supports * 2.5 mm wall and bottom thickness * Up to 3 mm thickness around rails * Approximately 2 mm lid thickness * Rounded external corners, about 4 mm radius * Straight, square internal corners * Modern, minimalist electronics-product appearance The lid must slide along the longest dimension. It should enter from one short side and slide through rails integrated into both long sides of the lower body. Use a simple tongue-and-groove or shallow dovetail rail system suitable for PETG FDM printing. Rail requirements: * Approximately 0.30 mm clearance between mating surfaces * 0.30–0.35 mm vertical clearance * Chamfered rail entrance for easy insertion * Lid must not lift vertically when engaged * Add a stop at the fully closed position * Rails must not reduce the required internal space * Avoid fragile sections, difficult undercuts, and unsupported overhangs Add a small snap-fit locking detent inside one rail near the fully closed position. Detent requirements: * Rounded or hemispherical bump * Approximately 1.6 mm diameter * Approximately 0.5 mm protrusion * Matching shallow recess in the lid * Must create a light tactile click * Must hold the lid closed but still allow manual reopening * Must not require screws, glue, or separate parts Manufacturing: * Bambu Lab A1 Mini * PETG * 0.4 mm nozzle * 0.20 mm layer height * No supports Print the lower body upright with the opening facing upward. Print the lid flat. Ensure both parts are watertight solids, correctly scaled in millimeters, non-intersecting, and exportable separately as STEP and STL files. Prioritize dimensional accuracy, smooth sliding, reliable snap retention, support-free printing, and simple functional geometry.

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.
