This is a simple grabbing claw for the Makeblock mBot, specifically matched to the little 9g servo that comes in the mBot servo add on kit.
I saw [this great

claw for a micro servo by Kepler](https://www.thingiverse.com/thing:18339), as well as [a remix of the claws by Sidertis](https://www.thingiverse.com/thing:984360) and thought that they would work well with the [Makeblock mBot add-on servo pack](http://store.makeblock.com/mbot-add-on-pack-servo-pack).
I made a few little changes so that it would work better with mBot, especially for young tinkerers.
1. I added this [mBot-sized mounting plate](https://www.thingiverse.com/thing:761418) by maxjenius to the servo box from Kepler's model so there would be something to attach to, and that things would square up nicely on the mBot frame.
2. I made some edits to hole sizes and the recess for the nut so that it can use all mBot hardware (m4 bolts and nuts).
[I put it together in Tinkercad, so feel free to edit it there.](https://www.tinkercad.com/things/1bbqR13OB4j)
