Taurus G3 Magazine Loader / Load Assist Device

This Taurus G3 magazine loader was designed from the ground up with strength, durability, and smooth operation as the primary goals. Every design decision focuses on eliminating common failure points found in weaker mag loaders while keeping the print practical and repeatable.

Rather than relying on infill, this model uses 9 solid perimeter walls, creating a dense, impact-resistant body that resists flexing and cracking under repeated use.

The load post, which absorbs the most force during operation, features filleted transitions where it meets the base to reduce stress concentration. A height range modifier is intentionally used when printing:

• Larger layer heights through the post for maximum strength
• Smaller layer heights in the upper geometry to improve surface finish and overhang quality

Most overhangs are kept at 45 degrees to avoid unnecessary supports; however, there is one vertical (90°) region that does require supports. This area is designed with a flat surface, making support generation clean and predictable, with easy removal after printing.

For improved handling, the side faces use a fuzzy skin texture, adding grip without increasing bulk—especially helpful during repeated loading sessions or when hands are tired.

The magazine insertion area is chamfered, similar to a flared magazine well, ensuring smooth and consistent insertion during use.

Features

• Designed for Taurus G3 magazines
• 9 walls for maximum durability
• Filleted load post base to reduce stress and cracking
• Height range modifier for strength where it matters most
• Mostly self-supporting geometry with one intentional supported region
• Chamfered magazine entry for smooth alignment
• Fuzzy skin side texture for improved grip

Printing Notes

• Supports required only for the single vertical region
• Flat support interface for easy removal
• Height range modifier strongly recommended
• Prints cleanly in PLA, PETG, or tougher filaments
• Oriented for reliable flat printing

Built to be used, not babied—this loader prioritizes real-world durability, print reliability, and ergonomic handling.
