Anyone punched someone and recorded it yet? haha

When you printed this, did you use any supports for the 90 degree gorpo mount?

Yes, use support

Great model! I used this with my AKASO EK700 4K Action Camera ( http://amzn.to/2tw491R same exact thing as a GoPro but only $55!) and it works perfectly!

Maybe just my setup as im new to 3D printing at moment but i found it better printed the other way around with the nut part at the top, i find it makers a better job of the nut shape. good job pal i printed it for a mate who was made up with it. THANKS

Yes actually it might come out cleaner the way you did, happy that you liked it

Takes a long time to make but worth it. The screw is not included

To not miss one punch unleashed to your Enemies
Hahahah awesome

Esas moneditas yo las reconozco!, saludos mi mexa!

123mmx64mm 20mm thick

I'd really like to see a video!

I'm imagining something like a Rocky training sequence, with this angle spliced in, but whatever floats your boat!

I would like to see it too :D

i need to use M5? did not enter to it...

Standart nut and screw should fit, beware of plastic shrinkage if you are using ABS

Well... I don't care if it's illegal in my country. Life is short. :D

I guess it's legal everywhere, because Brass Knuckles are made out of.. well.. brass?
So these are totally legal Plastic Knuckles! ツ

Cool design!

You are right but some places have ridiculus laws or rules, they did not let me into a mall because of pliers (5cm long)... and I missed Starwars :(

How do do you put the Gopro?

after print the holes Too thin for the gopro case, There is not enough profit and it is broken..

Did you printed it in abs, keep in mind that there will be plastic shrinkage. I designed it for pla printing. Try scaling it up a little (by 1.01)

No, Print with PLA

Thanks i will try :)

I love the fact we are getting to the stage where we can print almost anything and I think this is a really cool design. I just wanted to remind people not every country allows you to make knuckle busters like these and in my country it's illegal so just check your not braking the law.

That is exactly why I said, "check your regions laws". Thanks for emphasizing. It's sad that you can't print it :/

Using Simplify3D and it is having some issues with this .stl. For some reason when sliced the GoPro mount becomes a separate piece to the main knuckles, can't figure out why?

This screengrab illustrates the issue, any ideas why this is happening?


I repaired the file, It's been ages, sorry for that.

Oh great, will give it another go, thank you!

It's interesting, I will look into that. By that time, you can slice it with cura, it slices out okay

Great if someone tries to steal your camera!! :)

I'm glad you have found a new use for my design! Other than a paperweight that is.. lol

Haha, thanks :D
