Model origin

The author remixed this model.

Differences of the remix compared to the original

Enjoyed the 2.5" Three Jaw Chuck by mdkendall, however, the chuck kept falling apart after the slightest torque.  

Modified C-Clip:
The retaining C-Clip would pop out easily.  I thickened the clip, increased the amount the circumference engagement, and added a stiffener to keep the clip from deforming as easy. 
 

New Threaded Hex Bit:
I needed a method to mount to my drill, and I didn't want to glue.  The original model has threads, so I decided to use them.  This allows a nice mount that can be easily removed.
0.2mm layer height maximum for the threads.
