About This Software

DESIGN, UNFOLD, PRINT, BUILD

SHIRYU is paper craft design software for creating original printable paper models. Build a 3D model on screen, unfold it into paper parts, arrange the printable layout, and assemble the real object with paper, scissors, and glue.

JURY-SELECTED ROOTS, EXPANDED FOR STEAM

The original paper craft modeling software by Takahiro Yonemura was named a Jury Selection in the Entertainment Division of the 10th Japan Media Arts Festival. This Steam release is its expanded and improved successor, carrying that creative concept forward with more models and enhanced features.

SHIRYU connects digital design with hands-on making for hobbyists, educators, makers, artists, and first-time paper craft designers.

KEY FEATURES

• Create and edit original paper craft models on your PC.

• Start with more than 70 ready-to-build included models.

• Convert 3D shapes into printable unfolded patterns.

• Edit and arrange paper parts before printing.

• Print templates for real-world assembly.

• Use your own original works commercially.

• Suitable for hobby projects, education, workshops, and creative prototyping.

SIMPLE TO BEGIN, OPEN TO EXPERIMENTATION

SHIRYU has been used successfully by elementary school students, yet it leaves room for careful manual work and inventive model design. Start from an included example, learn how the parts fit together, and move on to creating paper models of your own.

IMPORTANT NOTES

Final assembly requires paper, a printer, cutting tools, adhesive, and manual crafting work.

SHIRYU is intended for hobby, educational, and creative use. It is not industrial CAD/CAM software and should not be used where professional manufacturing accuracy, engineering tolerance control, or safety-critical precision is required. Small differences can arise from model geometry, printer settings, paper thickness, cutting, folding, gluing, and manual assembly.

Windows may display a User Account Control (UAC) prompt at startup or when printer settings are changed. Administrator permission is used for temporary file operations and printer configuration.

No generative AI was used to create the included models or the program code.
