SKREEE v2

SKREEE v2 Features

The SKREEE v2 stands out with its reliable auto sear mechanism, designed to seamlessly convert double-stack Glock variants into dual-mode firearms. This updated version includes separated STL files for easier individual loading and tightened tolerances on sears and backplates for enhanced precision.

• Multiple Sear Options: Includes four sears with varying lengths—L for G21-20, M for G17-19, and S for G26 and subcompacts—each marked for easy identification.
• Selector Indicator: Features a rear indicator to clearly show the current mode, ensuring user-friendly operation.
• XL Sear Addition: An extra-large sear option for larger or trickier frames, offering greater compatibility.
• Customizable STEP Files: Provided for remixing or learning, allowing users to adapt the design to their specific requirements.

This design prioritizes functionality while acknowledging the need for user discretion due to its NFA-style classification. Note that Gen 5 frames may require modification due to a sear block, which should only be attempted by qualified individuals like FFL 07/02 holders.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 6-8 hours
• Required Experience: Familiarity with 3D printing, firearm mechanics, and local laws/regulations is essential before attempting this build.

Hardware and Tools Required

Required Hardware

• Glock Frame: Compatible with OEM Gen 1-5 double-stack Glocks (Gen 5 may require modification).
• 3D Printed Parts: Auto sear components as provided in the STL files (L, M, S, and XL variants).
• Material: PLA+ or stronger material for durability and performance.

Recommended Tools

• 3D Printer with support capabilities
• Basic firearm assembly tools (punches, screwdrivers)
• File or sandpaper for post-print finishing
• Digital caliper for precise measurements

SKREEE v2 Parts

The SKREEE v2 package includes separated STL files for each component, making it easier to load and print individual parts like the sears and backplates. The files cater to different Glock models with specific sear sizes—L for larger frames like G21-20, M for mid-size G17-19, and S for subcompacts like G26, each labeled on the flat surface for clarity. Additionally, an XL sear is provided for challenging frames, alongside a selector with mode indicators.

For optimal results, use a nozzle temperature of 220°C, a bed temperature of 60°C, a wall count of 20, and 100% infill to ensure strength. The design requires supports during printing, and while orientation is predetermined in the STL files, users must exercise judgment if adjustments are needed. STEP files are also included for those who wish to modify or study the design further.

Printer Compatibility & Settings

The SKREEE v2 is compatible with most FDM 3D printers capable of handling detailed prints with supports. Recommended materials include PLA+ or stronger alternatives to withstand the mechanical stress of firearm components. Ensure your printer can maintain the specified settings—220°C nozzle temp, 60°C bed temp, 20 wall count, and 100% infill—to achieve the necessary durability.

Special considerations include the need for supports during printing and careful attention to local laws, as this is classified as an NFA-style item. The predetermined orientation in STL files should generally not be altered, and users are encouraged to review the build instructions PDF for additional guidance.

Conclusion

The SKREEE v2 offers an unparalleled opportunity for 3D printing and firearms enthusiasts to explore a reliable Glock auto sear design with versatile compatibility across Gen 1-5 models. With detailed files, customizable options, and precise tolerances, it’s a valuable educational tool for understanding firearm mechanics—provided users adhere to local laws and regulations.
