Wearable Cooling Tank Body

Design only a compact, 3D-printable rectangular water tank for a wearable cooling-jacket system. Requirements: - Usable water capacity: 1.5 liters. - Design the tank with approximately 1.6–1.7 liters total internal volume to leave some air headspace above the 1.5 L water level. - Make the tank compact and lightweight. - Use rounded external corners suitable for 3D printing. - Create a rigid tank body with uniform wall thickness. - Target wall thickness: 2.5–3 mm. - Material assumption: PETG or ABS. - The tank should be a single main reservoir body with a removable top/filling cap. - Provide a large filling opening on the top of the tank. - Use a screw-type filling cap. - Add an O-ring groove/sealing arrangement under the filling cap to make the cap leak-resistant. - The filling opening should be large enough to easily fill 1.5 L of water. - The cap should be easy to remove and tighten by hand; add external grip ribs/knurling to the cap. - Keep the top surface generally flat around the filling opening. - Add small external ribs only where necessary for structural strength; avoid excessive features. - Do not design the pump, electronics, tubing, manifold, air vent, mounting brackets, or other components. - Do not add any pipe ports or connectors. - The only functional feature besides the tank body should be the top filling opening and removable filling cap. CAD requirements: - Create the tank as a fully parametric Fusion 360 design. - Create user parameters for: - Usable water volume = 1500 mL - Total internal volume = approximately 1650 mL - Wall thickness = 2.5–3 mm - Filling opening diameter - Tank width - Tank depth - Tank height - Calculate the actual internal volume and adjust the tank dimensions until the total internal volume is approximately 1.6–1.7 L. - Clearly show the calculated internal volume in the design. - Ensure the tank is manufacturable using FDM 3D printing. - Avoid unsupported overhangs where possible. - Keep the tank geometry simple enough to print and assemble. - Design the filling cap and O-ring groove as separate components. - Include a small chamfer/fillet on sharp edges for safety and better printing. Do not design anything other than: 1. Water Tank Body 2. Filling Cap 3. O-ring sealing feature Focus only on the tank geometry and 1.5 L water-storage capacity.
