Since InMoov hand has been released on Thingiverse, I receive demands on how to use it as a prosthetic. Lately a french FabLab asked me if they could use InMoov for their project. I knew the initial design was not adapted for that matter and I think it could be better done if I kept the prosthetic perspective in mind.
So this research can be used for the Bionico Prosthetic project or any other prosthetic project as long as it is not with commercial uses.
The goal is to keep all motors within the palm and to create mechanicaly actuated fingers.

This finger has two types of motors, make sure to download the correct casing and FingerWorm for your purpose.
This is meant to be assembled using a servo motor Corona DS238HV or a DC brushless motor with planetary reduction 154:1
from Pololu.
The motor used:
The driver used

With the servo Corona DS238HV use these files:

With the planetary gear motor use these files:

Update 18/07/13 PhalangeV1 is now PhalangeV2.
Update 20/07/13 PhalangeV2 to PhalangeV3.
Update 23/07/13 PhalangeV3 to PhalangeV4, ActuatorV1 to ActuatorV2
Update 24/07/13 PhalangeV4 to PhalangeV5
Update 25/07/13 ServoHolderV1 to ServoHolderV2 to get more flex on the finger
Update 13/08/13 PhalangeV5 to PhalangeV6 for even better flex. Added MotorHolderV3mid and MotorHolderV3mid for the planetary gear motor.. Added FingerWormV2 for the planetary gear motor.

There is no instructions yet, as this is a work in progress.

Where do you have a left hand version? I´m trying to make a prosthesis for a guy who has lost his arm. Thank you for your work.

hello, can you send me all 3d models for this hand. not for the finger. I tell about prosthesis on the main page.
I very need it for my progect.
Thank you.

I am at new with these things and ı wonder which programs do you use to draw them. Thanks

Sorry, what about palm parts?

Is there any tutorial on how to assembly this finger? I'm trying to build myself a prosthetic hand and your design looks just perfect.

can i get the whole model of the hand please. actually i wanted the files of hand that uses dc planetary gear motor.. help me

thanks in advance

Has this progressed much further? I love the design and would love to test it for several applications I have planned.

I'd also like to review this for the eNABLE group.


Hi, I am a Colombian college student and I wanted to ask if I can use this as a basis for mi project. I would apretiate any help you could give as well as the files you could provide. Thanks

we are french students and we are working on a project for school. This project is an artificial limb. We are using your project and we would like to have your mounting scheme. Thank you in advance.

Hi hairygael,
Is it possible to obtain the phalange gear file without the other phalanges and the actuator in two files. I wish to do the phalange in stainless steel and the actuators by water jet cutting a .dxf or .dwg file will be nice.

Hi, no thumb. :)

This is not a hand yet. it is only one finger and needs to be printed by beta testers, before to go on with the rest of the hand. Being away from my 3d printer, I can't test it, so I'm relying on others.
