HD22 by plastic blasters

HD22 by plastic blasters Features

The HD22 by plastic blasters stands out with its user-friendly design, making it accessible for builders of varying skill levels. Its ergonomic build ensures comfort during use, while the reliability of the design guarantees consistent performance with standard velocity .22LR ammo.

Key highlights include:

• Incredibly Easy to Print and Assemble: Streamlined for a hassle-free build process.
• Optimized for Standard Velocity .22LR: Designed to prevent burst cases when using appropriate ammo, with a weighted bolt pusher update for extra hot ammo (though premature bolt wear may occur).
• Regular Updates: Recent fixes include scaling issues with the cheek rest, buffer guide model adjustments, and an assembly video added on 8/20/2023 for visual guidance.

This PDW also features a remixed magazine design, incorporating the best aspects of popular models. It uses the same spring as a CMMG mag for smooth feeding and reliable operation.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 8-12 hours
• Required Experience: Basic knowledge of 3D printing and firearm assembly; familiarity with handling materials like PLA+ and tools like razors for post-processing.

Hardware and Tools Required

Required Hardware

• Barrel Liner: Pre-chambered Chaszel liner recommended for optimal performance.
• JB Weld: For securing the barrel liner in place after heating and removal from old versions.
• M3 Bolt (Optional): For extra security when holding the ramp in place.
• Magazine Spring: Compatible with CMMG mag springs for the remixed magazine design.

Recommended Tools

• Oven: For heating PLA+ at 250°F to remove and reuse old barrel liners.
• Razor Blade: For scraping off old JB Weld safely.
• Sandpaper or File: For adjusting the ramp fit and bolt round pickup if feeding issues occur.
• Basic Hand Tools: For assembly and minor adjustments during the build.

HD22 by plastic blasters Parts

The HD22 by plastic blasters file includes all necessary STL components for printing this .22LR PDW, covering the core design and updated parts like the cheek rest and buffer guide. The package also contains a remixed magazine design for reliable feeding. For detailed assembly, an instructional PDF guide is available at this link, alongside an assembly video updated on 8/20/2023.

For printing, use PLA+ as the primary material to ensure durability while maintaining ease of printing. Pay attention to areas like the spring channel and ramp fit, as minor filing may be needed for smooth operation. Print with a high infill percentage (around 80-100%) for structural integrity, especially in high-stress components like the bolt and magazine.

Printer Compatibility & Settings

The HD22 by plastic blasters is compatible with most consumer-grade FDM 3D printers capable of handling detailed prints. Recommended materials include PLA+ for its balance of strength and printability, though users should avoid weaker materials like standard PLA for critical components. Ensure your printer bed is leveled and can accommodate the part sizes, as some components may require larger build volumes.

Optimal settings include a layer height of 0.2mm for detail, a nozzle temperature of 200-220°C for PLA+, and a bed temperature of 50-60°C. Use supports where necessary, especially for overhangs in the magazine and bolt areas. Post-processing, such as sanding or filing, may be required to ensure a snug fit for parts like the ramp and bolt pickup.

Conclusion
