silica gel container 3d model

Create a functional 3D printable silica gel container for Bambu Lab A1 using PETG-HF. Dimensions: 185x75x20 mm. Rectangular industrial CAD-style design with rounded corners and chamfered edges. Fully ventilated honeycomb mesh on top, bottom, and sides for maximum airflow while preventing silica gel leakage. Add 4 integrated 4 mm bottom feet for airflow underneath. One 75 mm side must be a sliding refill lid with rails, one-direction movement, and a mechanical end stop preventing full removal. Wall thickness 1.6–2 mm, mesh holes 2–3 mm, slider tolerance 0.25–0.35 mm. Reinforced lightweight structure, support-free FDM geometry, optimized for 0.4 mm nozzle printing, clean hard-surface topology, dimensionally accurate, print-ready mechanical prototype with realistic manufacturable details.
