The prompt
Design a fully parametric 3D-printable main chassis for a professional outdoor WiFi koi feeder. Requirements Overall size: 240 × 240 × 185 mm Material: ASA (PETG-CF compatible) Wall thickness: 3.5 mm Corner radius: 18 mm Internal structural frame only; exterior panels are non-structural. Modern square industrial design with hidden fasteners. Fully parametric (all dimensions driven by user parameters). Features Upper flange with EPDM gasket groove for removable hopper. Front-loading electronics tray on integrated rails. Battery compartment for 12V LiFePO₄ below electronics tray. Bottom mounting interface for removable dosing cassette. Internal cable ducts. Drainage channels to keep water away from electronics. Labyrinth ventilation. Internal ribbing for stiffness. Four corner towers with M3 heat-set insert pockets. Hidden snap-fit mounts for removable side panels. Rear keyhole wall mounts for M6 screws. Design Rules No supports required for printing. Maximum overhang: 45° Rounded internal corners. Uniform wall thickness. Injection-molding friendly geometry. Easy assembly and maintenance. Deliverables Parametric CAD assembly Individual components STEP STL Exploded assembly Engineering drawings Bill of Materials Mass and interference analysis Design style: Premium commercial koi feeder, similar to FIAP or Sweeney products, with clean industrial aesthetics and modular construction.
