I want to replace a single 33 × 33 cm Kallax cube with a neat three-drawer insert molded entirely in polypropylene. The drawers have to sit on smooth runners, open comfortably without any external hardware, and look completely handle-free—think a subtle finger hole cut-out or a similar integrated grip. Colour matters: please prepare the model so I can offer a small palette—soft pastel shades that work in either a boy’s or girl’s room, along with classic white and a warm brown. The shell itself can stay neutral; the colour call-out is mainly for the drawers. What I need from you is a production-ready design: • Detailed 3D CAD (STEP or similar) sized precisely for a standard IKEA Kallax cubby • Exploded views or assembly instructions showing how the carcass and three drawers fit together • Basic material and wall-thickness notes suited to polypropylene injection moulding • A quick render set so I can visualise each colour option before tooling If you have experience designing plastic storage products or working within IKEA tolerances, this should be straightforward. Let me know your approach and any previous projects that show you can hit these specs.
