I created a 3D-printed version of the finger chopper. Design isn't identical to the original, but it obviously works on the same principle.
It is printed in a green-ish plastic with infused glitter particles, so it has a certain sparkle to it. The hinge is integral, and the hinge pin is just a piece cut off of a paperclip. That's the only part which is not 3D-printed. Link to picture 1 Link to picture 2 |

Mroek, that looks great! What printer do you use and what material?

The plastic used for this one is Fillamentum's Vertigo Galaxy:
https://fillamentum.com/products/pla-ext......o-galaxy I have two printers, but this was printed on a Craftbot 2. This is from a Hungarian manufacturer that started off on Indiegogo, and has been quite successful after that. Very happy with the printer, perhaps especially because it has a touchscreen and a efficient user interface. On my other printer I have a traditional click-and-rotate control wheel, which is awfully slow to use compared to a responsive touchscreen. |

That material looks good.
I'm still on my first printer, a Da Vinci Mini. It's a good starter printer. I'll upgrade eventually. |

In general, Fillamentum is very high quality filament. And it's the only filament I have seen which is actually perfectly spooled. The spools actually look like this when you open them:
I realize it doesn't actually matter, but it is rather satisfying nonetheless. |

Filamentum looks really good. Unfortunately for me, the Da Vinci printer requires proprietary spools. The have a circuit board attached with info that the printer uses.

Yes, Da Vinci is rather famous for claiming to be "open", while still being more or less completely closed. They actually don't even understand what "Open source" means. Now, open source is in no way a requirement (and my own main printer is also closed source), but locking users into proprietary consumables is always a no-go in my book.
For that reason, if one day you are buying a new printer, make sure it is open in the sense that you can use any filament. |

Mrock...
That is a fabulous result! It amazes me what people are doing now with 3D printers and magic. We actually have our first company in magic producing wonderful tricks - all 3D printed. (3D Magic Works) I have been researching Edward Massey for over 35 years. He is the inventor of the 1st finger chopper (the famous one with the pivoting blade.) Most magicians don’t know that Massey invented it. I became so enamored with the little finger chopper that I begun a collection of them. I likely have over 70 of them (have lost count over the years.) The Clarence Miller version - ironically so - was modeled after another Massey trick - the Penetrable Card. I would LOVE to have one of your choppers in my collection. The trouble is I don’t have a 3D printer nor any access to one. Is there ANY way I could pay you to print me one? It would mean a lot to me to be able to have this 21st Century interpretation of the famous trick. Please advise - and thanks for the consideration. Rhett |

Rhett, thank you very much for your kind words and interesting history lesson. I did not know any of that, so thanks for enlightening me!
I am well aware of Kent's excellent work with his 3D Magic Works, and he really is breaking new ground with that. 3D-printing really lends itself beautifully to creating a lot of magic props and gimmicks, and he's the first one to make a business from it. Now, for my finger chopper, some additional notes. It has been printed in an orientation that does not maximize strength of the parts, but instead best hides the secret, and as such some care must be taken to avoid breakage. This printing orientation also causes the movement of the blade to make quite a bit of sound, which I guess could be either a blessing or a curse, depending on preference. I don't mind, because it adds some additional drama. |

So is the op about a product for sale or are we encouraged to print our own? If the latter, is there a link to the .cad files?
No matter how many times you say the wrong thing, it will NEVER be right.
If I'm not responding to you? It's because you're a TROLL! |

No, I consider this to be a bit too fragile for regular use, so no production of these. And I don't want to share the files either, sorry. It was more of a test to see if it was possible than something suitable for normal usage.

Looks awesome .

Looks great. I'm just getting out 3D printer up and running and have a couple of ideas to try out. What software did you use for your design?
|
mroek Regular user 180 Posts |
Kevin, I do all my design work in Autodesk Fusion 360. It is free for hobbyists, at least until they decide it isn't.
