KURT-gobang 12 gauge shell v2

KURT-gobang 12 gauge shell v2 Features

The KURT-gobang 12 gauge shell v2 stands out with its experimental yet practical approach to printable ammunition. This design supports multiple ignition types, including 209 primers and .22 LR Ramset, giving builders flexibility in assembly.

Key enhancements in this version include:

• Tightened Primer Pocket: Ensures a secure fit for ignition components, reducing the risk of misfires.
• Beveled Sabot Design: Simplifies projectile insertion, making the assembly process smoother and more efficient.
• Global Compatibility: Usable with standard 3/4-inch piping, making it accessible to builders in any country with a 3D printer.

Safety remains paramount, as the design emphasizes caution with powder charges to prevent dangerous overpressure. This shell is a perfect blend of innovation and practicality for those passionate about custom firearms projects.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 4-6 hours
• Required Experience: Basic knowledge of 3D printing, familiarity with firearms safety, and experience measuring powder charges accurately.

Hardware and Tools Required

Required Hardware

• 209 primer or .22 LR Ramset for ignition
• Shotgun powder (e.g., Hodgdon Triple 7 black powder, up to 40 grains recommended)
• 20-gram casted projectile or equivalent
• 3/4-inch piping for compatibility

Recommended Tools

• Ramrod or hammer (appropriate diameter for seating primer)
• Powder measuring tools for precise charge loading
• 3D printer for shell fabrication
• Safety gear (gloves, eye protection) for handling powder and assembly

KURT-gobang 12 gauge shell v2 Parts

The KURT-gobang 12 gauge shell v2 file includes the necessary STL components to print a fully functional shotgun shell casing. Recommended print settings include a high infill percentage (80-100%) to ensure structural integrity under pressure, with layer heights of 0.2mm for precision.

For materials, PETG or ABS is suggested due to their strength and heat resistance, critical for withstanding the forces of ignition. Special considerations include thorough post-print inspection for cracks or weak points, as safety is non-negotiable with this experimental design. Detailed assembly instructions are available in the accompanying PDF guide at this link.

Printer Compatibility & Settings

The KURT-gobang 12 gauge shell v2 is compatible with most consumer-grade FDM 3D printers capable of handling durable materials like PETG or ABS. PLA is not recommended due to its lower strength and heat resistance, which could compromise safety during use.

Optimal print settings include a nozzle temperature of 230-250°C for PETG or ABS, a bed temperature of 80-100°C, and a print speed of 40-50 mm/s to ensure accuracy. A brim or raft may be necessary to prevent warping, and supports should be used if the design includes overhangs. Always test-fit components post-print to confirm proper dimensions before assembly.

Conclusion

The KURT-gobang 12 gauge shell v2 offers an unparalleled opportunity for 3D printing and firearms enthusiasts to engage in a truly experimental project with practical applications. With its updated design features and detailed safety guidance, this printable shotgun shell empowers builders to push boundaries while prioritizing caution.
