Bone Finger Updated

3D model description

Updated with a new longer three knuckle finger. It also has thinner side walls at the base. So it fits between your fingers a bit better .You can now print out four of these longer fingers. And use the original as the thumb. There is only one size finger for each knuckle Style. You must print multiple times.. I find using adhesive foam on the inside to size fingers accordingly helps. Finger holes are oversized. So should fit most people But no guarantees Sorry.. All models are split in half For easy printing. They must be glued together.Link to Assemble video

3D printing settings

I printed out at a point 1. In a point 2 layer height with 25% infill. I use the brim not necessary Depending on how well your bed adhesion is. But I do recommend supports..

If anyone is making these to sale hit me up I'm looking to get a set

These have been one of my favorite 3d printed thing. If the assembly is making you think twice - don't - it's actually really easy.

I just purchased these and was wondering if I can get the original 2 knuckle design as it fits more with my costume design. Sent you a message about it. Thank you

Bought and printed, can't wait for the backplate to stabilize the base knuckles.

@Gerhard: There's a part list and instructional walkthrough in the images above.

aaaaand bought. :-D Can you explain me the part names? how many times do i need to print a part for a 3 knuckle finger? A part list would be nice or a number in the file name like "3 knuc bone mid1_3x-stl" or so.

I will try and get it out this weekend thanks guys appreciate it

Standing by for the back plate. Love your work.

Is there a thumb V2 like with the dragon set?

I'm working on it currently I'm just printing the the back hand of the Dragon claw 2.0

Awesome print.
You wouldn't happen to have something for the back of the hand?

Printing the bars at 1.5mm thickness made the finger operate much more smoothly and easily.

Now to endure the long slog to print out the pieces for the other five.

Abumaia, I had the same problem, sanding the inside part of the fingers solved this. Also, the base part has to be tight on your fingers, if it's wobbly it makes extending the fingers much harder

I just successfully finished my first 3-knuckle finger. Flexing it is no problem, but I find it is rather tight and stiff when trying to re-extend it. I'm afraid my finger muscles are stronger in the gripping direction, not so much in the opening direction. I'm thinking of reprinting the two bars to be a little thinner, so they don't rub so much on the inside of the finger sections.

Hi Driagan
First thank you for downloading them I'm glad you like them. Yes I'll see what I can do about making a regular bone finger tip option in the future. As far as resizing the holes I found that the 1.75 filament is kind of the breaking point on the joints and raising the diameter a little bit along with printing them strengthen them up. And lastly as far as the holes on the bottom of the fingers the three knuckle updated version of the finger already has the holes. The two knuckle version does not have the holes maybe I will see what I can do about going in and slimming it down to better fit in between the fingers and adding a hole. I do also recommend using one-sided stick foam layered on the inside to better form to your fingers. I am so thankful to everyone in the community for downloading these and I hope you enjoy them as much as I have!

These look great, but I have three requests:
1. As someone else said, could the model use 1.75mm holes so that we can just use filament instead of having to print pins?
2. Could you also create human finger bone tips that could be used in place of the claw tips?
3. Could you add holes to the top back of the fingers that could be attached to a wristband with string or something to prevent the fingers from falling/sliding off?

Could you also upload the uncut files? Thanks

Any chance the model can be modified so the holes for the pins are 1.75mm so a section of filament can be used instead of printing pins?

can you post an assembly diagram or something?

Hey, thanks for making this!
I just downloaded the STLs, do you have a readme file that explains which parts to print?
For example when would I use mid1 vs mid2? What are all the parts I would need to make one 3 knuckle finger?

Hi blastin
It should . The longest piece is 111 millimeters. But I haven't tried it on my Photon yet due to the fact. The pins are set up to be made out of. PLA OR ABS. And have to be melted. To make like a riveting system to hold the finger together. You would have to come up with another solution. To put it together.

would the individual sections fit on an Ancubic Photon s Resin printer?
