Hello Patrick,  To view 3D print files you need a special program. Go online and find a program called Tinkercad. It's free. Load it and go check out tutorials on how to use it. It let's you look at, edit and build parts. Also find a program called Cura. It is the program a 3D printer uses to print a part. It will let you see what a printer will print. With these two programs all you need next is a printer to make stuff. Be Well Ron

By the way, the programs are free.

They show the hand in thingiverse.com also,  it is a work in progress and only one hand at this time. you will have to wait.  can't see how to add servo's as it is small.

hi nallycat

indeed i saw it on thingversie too.

No need for a second hand.  Just  mirror it in your slicer.  I don't think it would be functional, parts are too small.

hi 3dGuy

idd and no foam,so it cant grip anything.thanks for the respons.

What do you think if you took all  the 3D files available to print a JD  and enlarged the files. say to make a JD robot three feet tall. the EZ-Robot servos are strong, how big could you make a JD without resorting to having to add gears.  the body can be easy to enlarge the arms could just add extensions between the servos and the same with the legs.  I would make a new head though  I like eyes and a mouth.  and hands with fingers, hip servos and a MPU for balance, but all the programs for JD that are available could still be used.  more of a Robot less of a Toy.  does anyone think this could be done, a JD humanoid Synthiam Robot.

robot hand

thats some 90 cm tall.thats huge.these hands are good size for the mini meccanoid size. i think it can be done sinds there is a NAO robot,also a big one.but not affortable.

I have this  hand on my JD and it fits pretty good and works ok.....Looks like the template to 3d version.... https://www.ebay.com/itm/New-Humanoid-5-Fingers-Manipulator-Clamp-Right-Hand-With-Servo-for-Robot-DIY/381748216280?epid=904151189&hash=item58e1f781d8:g:Kw0AAOSwp7tbSYua
