Fusion 360 Endoscope Housing Model
Budget: $30 – $250 USD
Technical Design Brief – 3D Model of Endoscope Housing (Fusion 360)
Project: Multifunctional Endoscope – Housing for camera, thermal sensor, and laser integration
Goal: Create a fully printable 3D model (STL/STEP) suitable for prototyping and later production.

2️⃣ Main Body (Tube)
1. Create a sketch on the front plane.
2. Draw an outer circle (Ø 12 mm) and an inner circle (Ø 9.6 mm).
3. Extrude to 180 mm length → New Body.
→ Result: Hollow cylindrical body for the main endoscope tube.
3️⃣ Camera Module (Head Section)
1. New sketch on front face.
2. Circle Ø 14 mm → Extrude 25 mm (Join).
3. Central hole Ø 5 mm → Extrude Cut for camera/laser opening.
4️⃣ Thermal Sensor Section
1. On the opposite side, new sketch Ø 14 mm → Extrude 25 mm.
2. Add 10×12 mm rectangular pocket for MLX90640 or FLIR Lepton sensor.
5️⃣ Cable Feedthrough
1. On side plane, mark point 30 mm from the rear end.
2. Draw circle Ø 4 mm → Extrude Cut (Through All) for cable opening.
6️⃣ Split for Assembly
1. Offset Plane at mid-length → Split Body by Plane.
2. Result: Upper and lower halves.
→ Add alignment pins (Ø 2 mm, depth 1 mm).
7️⃣ LED Integration (Illumination System)
1. 4–6 SMD LEDs (Ø 3 mm) arranged circularly around the camera opening.
2. Drill holes Ø 3.2 mm, depth 2 mm.
3. Add 1×0.5 mm wiring groove inside.
4. Optional: Transparent PMMA cover (0.5 mm) for light diffusion.
8️⃣ Standard Video Camera Mount
1. Camera module (e.g. OV2640 or MIPI-CSI 8×8 mm).
2. Mounting pocket: Ø 6.2 mm × 7 mm depth.
3. Two mounting pins Ø 1.2 mm.
4. Optional snap-fit ring for friction mount.
5. Distance between LED ring and lens: 3–4 mm.
9️⃣ Printing Preparation
- Material: PLA for first prototype
- Infill: 40 %
- Wall count: 3
- Layer height: 0.15 mm
- Orientation: horizontal, camera head facing upward
- Supports: automatic, under the head area only
10️⃣ Finishing
Deburr printed halves carefully.
Verify fitting of PCB, camera, and thermal sensor.
Optional: Lightly polish or coat inner surface with PTFE for smoother insertion.
11️⃣ Deliverables
- STL file (ready for 3D printing)
- STEP file (for manufacturing/CNC)
- Fusion 360 archive file (.f3d) with parametric structure
- Screenshots showing camera/LED placement and cross-section
12️⃣ Notes
For future manufacturing, the final model should be optimized for injection molding or CNC machining based on this prototype.
