AC Condensate Water Reservoir

Create a 3D-printable parametric water reservoir for an air conditioner condensate water reuse system. The reservoir must hold approximately 1 liter of water and be designed for FDM 3D printing using PETG. Create a compact rectangular reservoir with approximately 3 mm wall thickness, rounded external corners and a removable top lid. Include: One water inlet opening on the top. One reinforced water outlet on the lower side of the reservoir. The outlet must be designed around a 1/4-inch connection. The outlet must have a reinforced cylindrical boss with significantly increased wall thickness around the connection to prevent cracking or breaking during installation. At the end of the 1/4-inch outlet, create a slightly reduced-diameter smooth hose barb/spigot suitable for connecting a small flexible water hose. The hose connection should have a gradual transition rather than an abrupt reduction. Add a small retaining ridge/barb near the end of the outlet to prevent the hose from slipping off. The outlet must have generous fillets at its base where it joins the reservoir wall to reduce mechanical stress. Keep the outlet thick enough to withstand repeated hose installation and removal. The outlet should be positioned low on the reservoir so that most of the water can be drained. Include an internal mounting area for a small 12 V DC water pump. Keep the internal geometry simple and easy to print. Avoid unnecessary overhangs. The reservoir must be watertight when printed with PETG. Make all important dimensions parametric and editable. Initial target dimensions: approximately 150 mm × 100 mm × 80 mm, with an internal volume close to 1 liter. Important: prioritize mechanical strength around the 1/4-inch outlet. The outlet must not be a thin printed tube. Use a thick reinforced boss and generous fillets around its connection to the reservoir. Do not add decorative features. Prioritize functionality, strength, watertightness, easy FDM printing and easy assembly.
