Reef Probe Measuring Chamber with Flow Bypass

Create a highly optimized, fully integrated single-piece parametric 3D model (STL / KCL) for a compact, silent, and leak-proof reef aquarium probe measuring chamber designed for FDM 3D printing in PETG. 1. FUNCTIONAL PURPOSE & HYDRAULIC DESIGN: - Isolates 4 measurement probes (Neptune Systems: pH, ORP/Redox, Salinity/Conductivity, Temperature) and 1 Titanium Grounding Probe in a calm, bubble-free water volume. - Connected in-line with an existing UV filter circuit operating at 400 L/h flow rate using 16/22mm flexible tubing. - Integrated Passive Flow Bypass: Water enters via a 16/22mm hose barb connector at the bottom. An internal baffle directs ~80% of the high flow straight through to a primary 16/22mm main outlet barb, while gently diverting a small fraction of laminar, bubble-free water upward into the measurement compartment. This eliminates micro-bubbles and heavy turbulence around the sensors. - Closed Hydraulic Loop (Silent): Completely sealed/closed system to operate silently near living spaces. - Emergency Safety Overflow: An extra high-capacity emergency drain port/slot is positioned near the top above the normal operating waterline to discharge directly into the sump in case of main outlet blockage. 2. MONOLITHIC BODY & PROBE LOCKING MECHANISM: - Fully integrated/fused single-piece body (no removable lid or separate top cover that can be lifted by water pressure). - Top Plate Ports: Features 5 vertical circular ports with a 13.2mm inner diameter to fit 13mm (0.5 inch) probe bodies. - Gasket-Free Lock: Each port features an integrated 3D-printable threaded collet/compression clamp collar to mechanically lock each probe at adjustable depth above the waterline without requiring rubber O-rings or external hardware. - Integrated Mount: A solid rim hanger bracket is molded directly onto the rear wall, designed to slide over a glass sump rim thickness of 12mm to 15mm. 3. OPTIMIZED PRINTABILITY & FAST PRINT TIME: - Engineered for fast printing in PETG with zero fail rate. - Uniform Thin-Wall Architecture: Set outer and inner wall thickness to exactly 2.0mm throughout the entire model (outer walls, internal baffles, hanger). This eliminates unnecessary solid volume and infill, targeting a print time under 45 minutes on modern FDM printers. - Self-contained, support-free design utilizing 45-degree internal chamfers where possible.
