SmartMount V7.2 Rev.A (Simplified)

Create a fully parametric 3D CAD model of a ceiling mount for the TP-Link Tapo H110 Smart IR Hub. Project name: SmartMount V7.2 Rev.A Purpose: Design a minimalist ceiling mount for home 3D printing (FDM). The mount must remain completely hidden behind the Tapo H110 once installed, creating the illusion that the hub is directly attached to the ceiling. General Design • Circular base. • Diameter: 52.00 mm. • Thickness: 3.50 mm. • Flat upper surface for ceiling mounting. • Smooth rounded outer edge with 0.8 mm fillet. • Bottom face completely flat except for the mounting features. Mounting Holes Create two countersunk holes for drywall screws. Hole diameter: 4.2 mm Countersink: 90 degrees. The screw heads must be completely recessed inside the base. Place both holes symmetrically around the centerline. USB Cable Exit Create one cable channel on the rear edge. Width: 8 mm Depth: 5 mm Blend both ends with rounded corners. Pin Mounting System Create two integrated mounting pins. Center-to-center spacing: 32.00 mm exactly. Each pin consists of: Neck Diameter: 3.80 mm Height: 2.50 mm Head Flat mushroom-shaped head. Diameter: 6.30 mm Thickness: 1.20 mm Top surface slightly domed with approximately 0.4 mm radius. Apply a 0.5 mm chamfer on the insertion side of each head to guide installation. Apply a 1.5 mm fillet where the neck joins the base. The pins must be printed as an integral part of the base. Bridge Reinforcement Connect both pin bases using one low-profile structural rib. Height: 2.5 mm Width: 8 mm Blend both ends with fillets. This rib must remain hidden after installation. Sliding Lock The mount must be compatible with the original TP-Link H110 keyhole slots. The H110 is installed by: 1. Aligning the large openings of the keyhole slots with the mushroom heads. 2. Pushing upward. 3. Sliding linearly 6 mm until fully seated. 4. A built-in mechanical stop prevents further movement. The H110 is removed by sliding in the opposite direction and pulling downward. No rotation. No clips. No flexible tabs. No magnets. Appearance The mount should visually resemble official TP-Link Tapo accessories. Minimalist. Rounded transitions. No sharp edges. The mount must be completely hidden once the H110 is installed. Printing Optimized for FDM printing. Material: PETG or PLA+ No supports required. Print orientation: Base flat on print bed. Model Output Generate a fully parametric CAD model. Maintain editable sketches and construction history. Export compatibility: STEP (.step) STL (.stl) Use millimeters as units.
