The SPS is the only frame I know of that is patented and I believe it's the process of the core that is the patent, not the shape.

Below is 'The Three Amigos" by @XxDollarBillxX, one that some, including myself, believe the LBS is based on.

The 3 Mini Amigos - By XxDollarBillxX

Hey All, I wanted a small shooter so i designed a model for my hand. I now make this design available to the forum. Moderators. If there is an issue with me using the logo please PM Me. I Have made one of these so far, Its a great shooter. The middle palm swell turns out its a perfect size for...

As long as you aren't selling, I'm pretty sure any design is a free for all for personal use. No one can stop you from making a copy of a frame for home use. The patent police have bigger issues than a slingshot forum guy making a frame for personal use.

Most makers just ask, and it's common courtesy, to give credit to the frame maker you are copying or emulating.

The whole SPS patent is a giant can of worms that I never cared to open or had an interest in.

sorry but its not based on that .. the LBS is my design that I created after years of shooting the opfs . So if anything it's based on that. The LBS has curves that I added as it morphed over the years .. the 3 amigos template is just that.. a template .. glad to clear that up lol

If you say so.

But sorry, I still feel it's a copy of the "The 3 Amigos" with a few minor tweaks. I'd love to see scale versions of them side by side, in template form.

It wouldn't be the first time someone based a frame on someone else's design and made it for profit. It happens all the time.

I like the shot in the foot version.
finished and ready to shoot.

Well that's pretty cool!

For what its worth, I had no intent on selling for profit or anything. I made 2 slings based on the LBS but with a meatier thickness and finger holes as appreciation gifts for the 2 co-workers who got me into the hobby/sport.

You're all good. Even if you did sell, nothing is patented.

We got sidetracked with the LBS vs 3 Amigos discussion. Sorry about that.
