Ribbed Dish Soap Holder with Sponge Drain Lid

Create a 3D-printable decorative cylindrical kitchen dishwashing soap holder with an integrated sponge holder lid. 1. MAIN BODY – EXACT DIMENSIONS * Height: 100 mm. * External diameter: 100 mm. * External depth: 100 mm. * Perfectly circular cylindrical geometry. * Hollow interior. * Designed to accommodate a removable 500 g commercial solid dishwashing soap tub. * Smooth interior walls. * Wall thickness: 2.5 mm. * Solid bottom thickness: 3 mm. 2. EXTERIOR DESIGN – CONTINUOUS ROUNDED RIBS Cover the entire exterior circumference with closely packed vertical rounded convex ribs. Each rib must: * Have a smooth semicircular convex profile. * Extend continuously from top to bottom. * Touch and merge directly with adjacent ribs. * Form a continuous solid exterior surface. * Have no spaces or gaps between neighboring ribs. IMPORTANT: Create positive raised geometry, NOT recessed grooves. Imagine multiple rounded vertical sticks fused side by side, forming one continuous cylindrical surface. DO NOT create holes, recessed channels, separated rods, alternating grooves or negative spaces. 3. INDEPENDENT TOP LID WITH SPONGE DRAINAGE TRAY Create a separate removable lid that fits securely over the main cylindrical container. Lid dimensions: * Circular shape. * Approximately 100 mm external diameter. * Total depth: 25–30 mm. * Compatible with the main container. * Designed to be removable and easy to clean. The lid must have two functional components: A. OUTER FRAME: * Circular perimeter. * Smooth, rounded edges. * A small raised rim to prevent the sponge from sliding off. * A clean minimalist appearance matching the ribbed container. B. INNER DRAINAGE GRID: * Integrated perforated platform inside the lid. * Multiple evenly distributed drainage openings. * Openings must allow water to drain away from the sponge. * Grid must be elevated slightly above the bottom of the lid, creating a drainage space underneath. * Rounded edges and easy-to-clean geometry. * Strong enough to support a wet kitchen sponge. The sponge must rest ON TOP of the drainage grid, not inside the container. The lid must function as a small removable sponge resting tray. 4. ASSEMBLY AND MANUFACTURING * Main body and lid must be two separate 3D-printable parts. * Lid must fit securely without requiring glue. * Include a simple circular fitting lip or rim. * Ensure the drainage openings are actual through-holes. * All geometry must be manifold and watertight where appropriate. * FDM 3D printing compatible. * Minimize the need for support structures. * Export both parts as separate STL files. FINAL DESIGN INTENT A sophisticated minimalist kitchen accessory combining a decorative solid dish soap tub holder with a removable sponge drainage tray on top. Maintain the continuous rounded vertical ribs on the main body. Do not introduce gaps between the ribs. Prioritize functionality, easy cleaning, drainage and precise assembly.
