Ivan's Brass Catcher

Ivan's Brass Catcher Features

Ivan's Brass Catcher stands out with its robust functionality and customizable design, tailored for top-rail guns. This brass catcher has proven its durability, holding up through approximately 1000 rounds of use, as tested by its creator.

• Rail Mount Compatibility: Designed to securely attach to top-rail firearms like the AR-15 with M3 screws for a stable fit.
• Custom Bag Attachment: Allows for personalization with a user-made bag, attachable via drilled holes or binder clips for quick setup.
• Fireproofing Option: For added safety, consider treating fabric bags with fireproofing spray to mitigate risks from hot brass.
• Durable Assembly: Utilizes a 1/4-28 rod to connect the body to the mounts, ensuring long-lasting performance.

This design empowers users to create a tailored solution for brass collection, combining practicality with DIY creativity. Whether you're at the range or in a tactical setting, this catcher keeps your focus on shooting, not cleanup.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 4-6 hours
• Required Experience: Basic knowledge of 3D printing, drilling, and hand-threading hardware; familiarity with firearm accessories is helpful.

Hardware and Tools Required

Required Hardware

• M3 screws (for rail mount attachment)
• 1/4-28 rod (for connecting body to mounts)
• Fabric or material for creating a collection bag (user-sourced)
• Optional: Fireproofing spray for fabric bag safety

Recommended Tools

• 3D printer (for printing STL files)
• Drill (for creating holes in mounts and catcher lip)
• Hand-threading tools (for threading rod into catcher body)
• Sewing kit or binder clips (for attaching the bag)
• Measuring tools (for precise hole placement)

Ivan's Brass Catcher Parts

Ivan's Brass Catcher includes pre-oriented and correctly scaled STL files, ready for immediate printing. These files cover the main body, rail mounts, and necessary components for assembly. The creator recommends printing in ABS for durability, though PLA is also a viable option based on testing.

For optimal results, ensure your printer settings align with the material used, focusing on strength for parts under stress like the mounts. Special consideration should be given to post-print assembly, as drilling and threading are required. A detailed build guide is available as a PDF at this link for step-by-step instructions.

Printer Compatibility & Settings

Ivan's Brass Catcher is compatible with most FDM 3D printers capable of handling standard filament sizes. Recommended materials include ABS for its heat resistance and durability, especially given the proximity to hot brass, though PLA can work for lighter use. PETG could also be considered for a balance of strength and ease of printing.

Print settings should prioritize a high infill density (20-30%) for structural integrity, with a layer height of 0.2-0.3mm for detail and strength. Ensure proper bed adhesion and consider using a brim or raft for smaller parts like mounts to prevent warping. No special printer requirements are noted, making this design accessible to most hobbyist setups.
