three jaw chuck

This is the beginning of my automatic coil winder. the coil will to be fixed in the chuck.
The idea is to set a number of windings via Control interface, hit Start and wait until your coil is wound..
Next part will be a motor mount with light barrier for measuring the revoltions.

Last but not least, even if i prefer plain C on AVRs, I'll put it on a Arduino Nano + SainSmart Keypad with 1602 LCD.. May take some days since i never programmed Arduinos before.. XD

Haven't yet printed it but
