This design prioritizes both aesthetics and practicality, offering a rewarding build for those passionate about 3D printing and firearm replicas.
Difficulty & Build Time
- Skill Level: Intermediate
- Estimated Build Time: 20-30 hours
- Required Experience: Familiarity with 3D printing, assembly of small hardware, and basic knowledge of AR lower parts or firearm mechanics recommended.
Hardware and Tools Required
Required Hardware
- Assorted Screws and Nuts: M3 and M4 socket head cap screws in various lengths (M3x4, M3x6, M3x12, M3x55, M4x6, M4x8, M4x12, M4x16, M4x20, M4x40), plus M3 and M4 nuts for specific components like firing pin and bipod mount.
- Compression Springs: Stock music-wire steel spring (11" long, 0.36" OD, 0.298" ID) for buffer and mag, plus 4mm x 15mm springs for bipod and firing pin.
- AR Lower Parts or Springs: Option to use a complete lower parts kit (approx. $40) or printed versions for most components, excluding springs.
- Optional Metal Hammer: Choice between a printed hammer or a commercial metal alternative for durability.
Recommended Tools
- 3D printer with fine detail capabilities
- Allen keys or hex drivers for M3 and M4 screws
- Screwdrivers for small hardware assembly
- Calipers for precise measurement during assembly
- Sandpaper or finishing tools for post-processing printed parts
Baby Barrett Parts
The Baby Barrett file includes STL models for nearly all components, covering both the M82A1 and M107A1 variants with parts like the stock, handguard, bipod, recoil pad, and charging handle. Recommended print settings include a layer height of 0.2mm for detailed areas and 0.3mm for larger structural parts to balance quality and speed. Using a strong material like PETG or ABS is advised for durability, especially for functional components subject to stress.
Special considerations include ensuring tight tolerances for screw holes to avoid post-print drilling. Additionally, infill should be set to at least 20-30% for structural integrity, particularly for parts like the bipod and stock. Refer to the included PDF guide for detailed assembly instructions, available at the provided build link.
Printer Compatibility & Settings
The Baby Barrett is compatible with most FDM 3D printers capable of handling detailed prints, such as Ender 3, Prusa i3, or similar models with a build volume of at least 220x220x250mm to accommodate larger parts. Recommended materials include PETG for a balance of strength and flexibility or ABS for higher durability, though proper ventilation is required for ABS printing. Avoid PLA for functional parts due to its brittleness under stress.
Optimal settings include a nozzle temperature of 230-250°C for PETG or 240-260°C for ABS, with a bed temperature of 80-90°C. Use a 0.4mm nozzle for precision, and enable supports for overhanging features like the bipod or handguard. Ensure proper bed adhesion with a brim or raft to prevent warping on larger components.
Conclusion
The Baby Barrett offers an exciting opportunity to build a scaled-down Barrett AR22 replica with incredible detail and customization through its M82A1 and M107A1 variants. Perfect for intermediate 3D printing enthusiasts and firearm hobbyists, this project combines technical challenge with rewarding results.
