6-Shot Blaster (Semi-Automatic)

Build Your Own Six-Shot Blaster with Compliant Mechanism!

16.12.2024 Hotfix: Updated the trigger's spring design for improved durability and extended lifespan.

This 3D-printed Six-Shot Blaster is a simple, fun project for makers of all skill levels. Here's how it works and what you need to know to build and enjoy it:

• One-Part Blaster & Magazine: The blaster is designed as a single piece, so there’s no assembly required. The magazine is also 3D printed and holds 6 bullets.
• Important Printing Tip: The magazine requires a brim during printing to ensure success (my prints failed without it). After printing, make sure to carefully remove the brim for smooth operation. All parts are printed using PLA material.
• How It Works: Load the magazine with 6 bullets, slide it into the blaster, and you’re ready to go! Once you fire the last shot, the magazine drops out automatically. You can then quickly slide in another pre-loaded magazine from the top.
• Performance: Using the strong version, the blaster can shoot up to 3 meters. It’s loads of fun, especially when paired with the included 3D printable targets.
• Safety First: Please don’t aim at animals, people, or anything fragile. This project is not suitable for children under 3, as the bullets are small and could pose a choking hazard.
