š ļø Why We Redesigned This Specifically for Makers
We are releasing these GEN4 printable files to allow fans in restricted regions to experience our original design. We listened to community feedback and realized that our previous rubber band locking mechanism was simply too complicated for a DIY build. It required extra screws, T-sliders, and springs, which made assembly tedious and sourcing the right hardware a real headache for makers worldwide.
To solve this and make the build as accessible as possible, we completely redesigned the front-end. This optimized GEN4 version drops all that complex hardware entirely! Instead, it utilizes a brilliant, tool-less 6mm Carbon Steel Ball locking mechanism to securely clamp the rubber bands. Itās an elegantly simple, highly effective solution that makes printing, sourcing parts, and assembling this semi-auto slingshot incredibly easy!
šŗ Assembly Tutorial & Hardware Kits Coming Soon!
We are currently in the studio recording a dedicated, step-by-step assembly tutorial video specifically for this 3D printed semi-auto slingshot / auto-loading slingshot. At the same time, we are organizing and preparing official assembly hardware kits to make your build even easier!

š Upgrade to the Ultimate CNC Metal Experience
Before you start printing, please keep in mind that this 3D printed version is strictly for casual experience and understanding the mechanism. 3D printed plastic is inherently fragile and not suitable for long-term or heavy-duty use.
If you are looking for a sturdy, highly stable, and truly durable product, we highly recommend checking out our official CNC 6061 T6 Aluminum version. Our newest generations of these high-end mechanical toys are manufactured exclusively via precision aerospace-grade CNC machining, offering unparalleled strength, reliability, and aesthetics that plastic simply cannot match. For the authentic, high-strength official sporting product with worldwide DDP shipping, please visit our official store: š Official Website: autofling.com
ā ļø Extremely Critical Safety & Structure Warning
This 3D printed GEN4 auto-loading slingshot is NOT comparable in any way to the durability of our official CNC 6061 T6 Aluminum versions. To avoid breakage or safety issues:
- Low Power Only: Use only low-power, reduced-tension rubber bands. Do NOT use full-strength official bands on a printed plastic frame.
- Proper Technique: Always use the correct operating technique and properly grip the pouch with your rear hand.
- Shatter Risk: If the rubber band slaps the frame during release, the printed body will split or shatter immediately. Always wear eye protection.
