Recently, a well-known Canadian RV modification creator with over 410,000 followers on Instagram utilized the professional-grade 3DeVOK MT professional 3D scanner in a Mercedes-Benz Sprinter RV customization project, successfully completing multiple custom 3D retrofits. This case study demonstrates how a handheld 3D scanner simplifies Mercedes-Benz Sprinter RV customization through an efficient Scan-to-CAD workflow.

In this project, the creator upgraded the Sprinter’s overhead sunglasses compartment, transforming it from a storage space into an integrated lighting control panel through 3D digitization—achieving centralized lighting control while maintaining a clean, factory-style interior.

Watch the complete RV customization process in action.

Challenges of Converting the Overhead Sunglasses Compartment into a Master Control Panel

Because the modification is located in a highly visible and structurally complex area of the vehicle’s ceiling, the customization presented several technical challenges:

Complex curved surfaces: The factory sunglasses compartment is seamlessly integrated with the headliner, making it difficult for traditional measurement methods to capture accurate geometry.

Limited space with high functional demands: The new panel needed to accommodate CAN bus switch modules and wiring while ensuring ergonomic operation and a clean appearance.

High-precision fitment requirements: Due to its prominent overhead position, even minor gaps or poor alignment would compromise both aesthetics and structural integrity.

As a result, conventional manual measuring and trial fitting carried a high risk of repeated revisions and potential damage to the interior trim.

3D Digital Retrofit Solution: 3D Scanning + 3D Design + 3D Printing

Tim’s approach was built on a complete digital retrofit workflow, combining high-precision 3DeVOK MT 3D scanning, Fusion 360 for 3D modeling, and Bambulab 3D printing to achieve accurate, custom-fit interior components.

1. High-Precision 3D Data Capture

Without altering the original interior, he used the professional-grade 3DeVOK MT handheld 3D scanner to capture the Sprinter’s overhead control area using an infrared laser - hybrid alignment mode. No markers were needed—scanning started immediately, with frame rates up to 80 FPS—smoothly capturing the complete 3D data of the roof area to provide a reliable foundation for CAD modeling.

Next, Tim used 3DeVOK Studio to clean and optimize the scan data, removing redundant information, and exported the processed data as an STL file.

2. Retrofit Design Based on Real 3D Scan Data

The processed 3D model was imported into Fusion 360 to begin the retrofit design phase.

In Fusion 360, Tim used the scanned data to create an integrated control panel structure. The design specifically accounted for CAN bus switch modules, wiring, and routing space, defining the installation interfaces and internal volume during modeling. This ensured that the final component would fit precisely with the original interior while meeting all functional integration requirements.

3. Custom Control Panel with Bambulab 3D Printing

After completing the CAD design and verifying assembly fit, Tim manufactured the master control panel using the Bambulab H2S 3D printer. Considering the RV interior environment and requirements for heat resistance, structural strength, and long-term stability, Siraya Tech ASA-GF was selected as the printing material, offering both high-temperature durability and reinforced structural performance suitable for automotive interior applications.

The print was set with a 0.2 mm layer height, balancing efficiency with quality and dimensional accuracy. Once printed, the component required minimal post-processing and was ready for installation and use.

The final 3D-printed panel was installed directly in place of the original overhead sunglasses compartment, successfully integrating the CAN bus switch modules and wiring. The finished component fit seamlessly with the roof interior contours, maintaining the factory-style appearance while achieving a balance between upgraded functionality and aesthetics.

Results of the RV Customization Project

Through the digital workflow and 3D printing, the custom lighting master control panel was successfully installed in place of the original overhead sunglasses compartment:

- Fits tightly with the roof interior, with virtually no visible gaps

- Enables centralized control of multiple lighting circuits and auxiliary devices

- Structurally secure and reliable, requiring no modifications to the original interior

Why Use 3D Scanning for RV Customization?

- Faster than manual measurement

- Accurate CAD modeling

- Better fit for custom interior parts

- Reduced prototype iterations

- Ideal for one-off and small-batch production

Conclusion

This case clearly demonstrates the advantages of combining 3D scanning, retrofit design, and 3D printing in RV and automotive customization:

- High-precision 3D scanning with 3DeVOK MT captures accurate models, significantly reducing traditional measurement errors

- Retrofit design based on 3D scan data allows early verification of assembly feasibility, minimizing rework

- 3D printing enables rapid fabrication of complex custom components, supporting small-batch or one-off production

This digital workflow provides a replicable and scalable 3D technology pathway for RV modifications, automotive customization, interior upgrades, and complex curved-surface designs.
