This is one finger for a Lego Technic gripper as used in the Mindstorms NXT 1.0 set (8527)
Unfortunately the new NXT 2.0 set (8547) contains different components and the gripper parts are no longer in the box.
As a real Lego addict I wanted to be able to use these fingers for some real gripping action but could not find them available on the internet. OK, you got me ... I am not a real addict otherwise I would have found a 2nd hand NXT 1.0 for sale somewhere ;-)
The design mimics the original Lego design but is different on some details.
Update on 2-Feb-11: The edges looked a bit rough due to the layering so I added a fillet to make the edges more smooth. Also made the mounting holes for axle and pegs a bit wider to have an easier fit on standard Lego components.
If you do not want to paint the fingers yourself, just select your color. The Alumide fits very well with the original Lego components.
Also have a look at the "set of 4
", that set contains 4 grippers that are stacked together to create one larger part that is cheaper than 4 separate fingers.LEGO® is a trademark of the LEGO Group of companies which does not sponsor, authorize or endorse this site.
