The drill I used had a drive shaft attached to a kind of head,  this had an odd profile so I drew around it with and then scanned it into solid works. Once in solid works I used sketch points and spline tool to draw round the outline.
After this I saved it as an SLMD so I could use it on the CNC machine


Step 3: Step 3 - Cutting part

To cut the odd shape for the head I used a CNC machine and the SLMD file

The other parts to hold the motor and the gears were made using a metal lathe

The end result looked similar to this
