3D model descriptionThis creative design transforms the classic 3D printing Benchy into a submarine inspired by the legendary Nautilus. The model preserves the iconic proportions of the test boat while integrating submarine features.

With its rounded hull, stylized portholes and compact structure, this Benchy variant is both a reliable calibration tool and a striking collectible piece. It maintains the core purpose of testing printer performance while adding a distinctive visual identity.

Optimized for both FDM and resin printing, the model features clean geometry and smooth surfaces, ensuring consistent and reliable results across different setups.

A classic test model reimagined beneath the waves.

3D printing settings• Recommended layer height: 0.16–0.2 mm for calibration use• Use 2–3 perimeters to evaluate wall precision• 10–15% infill for standard testing• Print without supports for true benchmark comparison• Adjust speed and cooling to analyze performance• Ideal for comparing materials and slicer profiles• Resin printing enhances fine surface details
