The Thunderbolt V2 3D Printable AR10 Lower Receiver Parts

This downloadable file includes the STL files necessary to print the Thunderbolt V2 AR10 Lower Receiver, a critical component for your custom firearm build. For optimal results, print with high infill settings (80-100%) to ensure structural integrity under stress. We recommend using a strong material like PETG or ABS to withstand the rigors of firearm use.

Pay attention to layer adhesion and avoid weak spots by printing at a slower speed with proper cooling. Post-processing may be required to achieve a perfect fit with your upper receiver and lower parts kit. Refer to the included build manual for detailed assembly instructions and tips.

Printer Compatibility & Settings

The Thunderbolt V2 is compatible with most FDM 3D printers capable of handling large prints, such as the Ender 3 or Prusa i3 series, provided they have a sufficient build volume. For materials, PETG or ABS is highly recommended due to their strength and heat resistance, though advanced users may experiment with nylon for added durability. Avoid PLA, as it lacks the necessary toughness for firearm components.

Set your printer to a nozzle temperature of 230-250°C for PETG or 240-260°C for ABS, with a bed temperature of 80-100°C. Use a layer height of 0.2mm or lower for better detail and strength, and ensure proper bed adhesion with a brim or raft if needed. Always print in a well-ventilated area, especially with ABS, due to fumes.

Conclusion

The Thunderbolt V2 3D Printable AR10 Lower Receiver is a game-changer for firearm enthusiasts, offering a community-tested, reliable design that empowers you to build your own custom AR10.
