Made the EEZYbotARM V1  some time ago and I have had little luck with getting all to work smoothly with the small servos on the main arms.  I have burnt out several micro servos with too much load, so I decided to merge V1 and V2 bases to drive V1 arms.  This meant I had to also redesign the  drive arms to suit bigger servo output arms.  Attached are the 3 xxx.stl  files to do all of this. Printed with 0.4 nozzle at 0.2 layer height and 25% speed for the first layer.  The new upper base fits on the original servo base just fine.  You will notice the extra tabs on the upper arm to stop the unit bending up as it cools. They just break off when printing has finished.  Just to tidy everything up I have also designed a PC board to run the arm via bluetooth and an ATmeg 328 microprocessor programmed with the sw to run the robot arm via a Uno with a removeable ATmega 328 chip. Makes a board slightly bigger than UNO with a power socket for 6v for the servos and reduced power to the mega chip to 5v.  I will be etching the board tomorrow.
