Let's make a 3D printed OTF Knife

This is the ultimate fidget device! What should I 3D print next?

The UK: it's time to ban 3d printers!

Sending this to all my homies in London.

Very nice... Now let's just move this over to my lathe

Ender is such a good brand. On our smaller projects we use them and never fail us. Malfunctions happen but never did it break. Heats perfectly and is always super accurate. Glad to see people still using them!

Finally something I can do with the springs from broken pens

Now size it up, lengthen it, hook up the opener to a string, and strap it to the underside of your forearm.

Boom, 3D printed hidden blade. Now anyone with a 3D printer or a friend with one can join the Brotherhood.

The sound of the blade deploying is quite satisfying

Looks like a clean design, well done! And using a pen spring is clever, a new way to recycle a dead pen

I was thinkin about there other OTF when I saw the caption😂

[KayhoticGames]

Interesting idea to put the firing mechanism on the blade itself. Most OTF knives, mine included, are all in the frame. Neat.

Now I’m going to attempt to make a metal OTF knife based on this… wish me luck!

[Spongesgetti]

Tbh, that pen spring one of the goat inventions, useful for alot of projects

POV: you are pranking someone and the blade doesn't go in
