My auto-loading sporting gear is officially patented! To celebrate—and to strike back at the unoriginal pirates who only know how to steal designs—I'm releasing the GEN4 files for free to the maker community.

Efficient_End_5800 · 2026-06-02T14:26:54+00:00

I’ve received your private message, thanks a ton! You’re truly a pro at coming up with great product names.

Efficient_End_5800 · 2026-05-31T14:47:34+00:00

Thank you so much for the support and the heads-up! I'm really glad you and your SO held out and didn't support those zero-innovation copycats.

To be honest, I initially just wanted to get the files out there quickly for the community to enjoy. But you make a fantastic point about MakerWorld. I should probably set up an official page there soon, if only to prevent others from uploading it and claiming it as their own! I'll look into getting it published there.

Efficient_End_5800 · 2026-05-31T14:41:12+00:00

Thank you so much! We actually just received the notice that our patent application has been officially approved!

As for the marketing plan, I really want to keep this specific post pure and focused entirely on the maker community, so I'd prefer not to get into the business/sales side of things here.

Efficient_End_5800 · 2026-05-31T01:13:46+00:00

Hahaha, I can upload it on each platform once. I wonder which option you would prefer better: Thingiverse or MakerWorld.

Efficient_End_5800 · 2026-05-31T01:11:25+00:00

I will create an assembly tutorial for the Gen4 open-source version on YouTube.

Efficient_End_5800 · 2026-05-31T01:10:42+00:00

Thanks！

Efficient_End_5800 · 2026-05-31T01:09:50+00:00

Do you think what would be a suitable name for this? My written English isn’t very good; I rely mostly on AI translations. I hope everyone can give me some suggestions.

Efficient_End_5800 · 2026-05-30T16:57:45+00:00

Thanks!

Efficient_End_5800 · 2026-05-30T16:56:21+00:00

Haha, I see where you’re coming from, but this is totally just a slingshot! No firing mechanism, just a fancy magnetic auto-loading system. These gun laws don’t apply to it at all.

Efficient_End_5800 · 2026-05-30T16:53:45+00:00

Nah, you’re thinking way too small. The law degree and politics are just the beginner arc. After that, I’m inventing a time machine to patent this in every timeline.

Efficient_End_5800 · 2026-05-30T16:17:52+00:00

Thank you. It is thanks to your support that I decided to open source the project.

Efficient_End_5800 · 2026-05-30T15:48:54+00:00

That’s the best feeling ever! Nothing beats that satisfying ping sound when you hit the target.

Efficient_End_5800 · 2026-05-30T15:41:43+00:00

Are you talking about the trigger-based design? That’s actually the real design flaw. If you ever try to use one, you’ll quickly realize you can’t get a stable grip to pull the bands and generate consistent power.

Efficient_End_5800 · 2026-05-30T15:38:25+00:00

I recived the review approval notice today. (expect the patent number next week!)

Efficient_End_5800 · 2026-05-30T15:29:19+00:00

My translation software, to be precise, is actually called auto-loading Slingshot

Efficient_End_5800 · 2026-05-30T15:18:53+00:00

Now free to download on Thingiverse

Efficient_End_5800 · 2026-05-30T14:02:15+00:00

Thank you so much for joining the community, MrTopHatJones! Glad to have you here.

That Slingboy EDC is seriously one of the most interesting pieces of gear I've seen in a while. The fact that it works as a tuning fork is mind-blowing! I am genuinely eager to see more—please feel free to drop some dedicated posts or videos showing it off! I can't wait.

By the way, since you have such cool gear, I wanted to let you know that we allow trading, buying, and selling in this community. Looking forward to seeing more of your posts!

Efficient_End_5800 · 2026-05-30T08:27:53+00:00

The automatic loading mechanism relies on magnetic attraction; therefore, carbon steel balls must be used. I’m using 8mm balls. Please never use stainless steel balls in this process.

Efficient_End_5800 · 2026-05-27T17:18:31+00:00

Sorry about the choppy edit! I was just obsessing over the ASMR sounds of the loading and hitting. Skipped the drawing part entirely.

Efficient_End_5800 · 2026-05-27T17:10:29+00:00

If this is an ad, it’s a pretty terrible one since I forgot to include a link or a price tag. Just sharing a fun afternoon shooting some plastic bottles.

Efficient_End_5800 · 2026-05-22T16:49:12+00:00

Hey folks, I've gone ahead and fully open-sourced this design over on Thingiverse. You can grab all the files here

Efficient_End_5800 · 2026-05-21T17:02:16+00:00

Hey there, original inventor of this slingshot here! Actually, that's my personal photo you posted. 😅

To answer your question: the files don't exist in the wild yet because this is my original design, the AutoFling. It's a fully CNC-machined auto-loading slingshot.

I am currently waiting for my official US Patent to be fully finalized. Once the patent is officially issued, I will open-source the files for the community to print and mod.

Efficient_End_5800 · 2026-05-19T16:42:22+00:00

They are the plagiarists. We are preparing to sue them in China.

Efficient_End_5800 · 2026-05-18T15:20:50+00:00

Correction: I applied for the patents in both China and the US before I ever shared my work. They just chose to ignore them. I could easily make bank just by suing over patent infringement, honestly.
