Three-Way Square-Tube Corner Connector

Create a Three-Way 90° Square-Tube Corner Connector Create a precise, fully parametric, one-piece corner connector for a Cube 1. Central Block * Solid cube: 10 × 10 × 10 mm * Position: X = 0–10, Y = 0–10, Z = 0–10 mm. 2. Square Tubing * Outside dimensions: 10 × 10 mm * Wall thickness: 1 mm * Nominal inside opening: 8 × 8 mm 3. Three Insertion Plugs Each plug measures 7.60 × 7.60 × 12.00 mm, with a square cross-section and slightly relieved longitudinal corners. * X plug: X = 10–22; Y = 1.20–8.80; Z = 1.20–8.80 mm. * Y plug: Y = 10–22; X = 1.20–8.80; Z = 1.20–8.80 mm. * Z plug: Z = 10–22; X = 1.20–8.80; Y = 1.20–8.80 mm. All three plugs must extend outward at 90° to one another and merge seamlessly with the central block into one continuous solid. 4. Edge Finishing * Add 0.5 mm lead-in chamfers to the tips of all three plugs. * Add small longitudinal corner reliefs to accommodate rounded tubing interiors. * Maintain nominal 0.20 mm clearance per side. * Do not add screw holes or other fastening features in Version 1. 5. CAD and Printing Requirements * Overall bounding box: 22 × 22 × 22 mm. * Units: millimeters. * Material: PETG. * Printer: Elegoo Neptune 4 Plus, 0.4 mm nozzle. * Recommend printing orientation and necessary supports. * Ensure one watertight, manifold solid with no disconnected bodies. * Validate the model’s dimensions and geometry before exporting. 6. Required Deliverables 1. Editable parametric CAD source file. 2. STEP (.step) solid model. 3. STL (.stl) printable mesh. 4. Dimensioned engineering drawing (PDF). 5. Isometric rendering showing all three plugs.
