I am building a standing, folding worm-farm that uses drawer-style trays and a base outlet tap for liquid collection, and I need a clean, production-ready 3D CAD model to bring it to life. The design must unfold by way of a simple hinge system, then lock into a stable vertical position where each tray can pull up and collapse down again smoothly. The joints and trays and removable screw in tap components need to fit properly for real world moulding. What matters most is well-defined geometry for every functional part—the frame, drawers, hinges, tap seat, and any stops or guides—so each piece can be manufactured or 3D-printed without guesswork. I will be working primarily from STL files, so please supply the finished model in that format, broken out by individual components rather than a single merged body. Deliverables (acceptance criteria) • Fully parametric 3D model with each part on its own STL file • Clear hinge alignment so the fold-out action is interference-free • Drawer/tray stack tolerances accounted for (easy slide, no wobble) • Threaded or press-fit detail for the outlet tap connection • Ideally a short PDF or image set that illustrates the folding sequence and final assembled stance No texturing or photoreal rendering is required; I only need accurate, fabrication-ready geometry. If you have hands-on experience designing foldable enclosures, drawer systems, or small-scale farm hardware, I’d love to see examples in your portfolio when you respond.
