Changed base for the Lite Arm i2 & S3 robot adapter

thingiverse

This is a modified version of the Lite Arm i2 base. The original design is the "Open Source Robotic Arm (Lite Arm i2)" found at http://www.thingiverse.com/thing:480446. The external appearance remains unchanged, but I've strengthened and simplified the base by reducing it to fewer parts. Several components from the original base have been modified or replaced with new ones. Specifically: 1) Part 1B.stl has been changed to 1B_NEW.stl. 2) Part 5B.stl has been updated to 5B_NEW.stl. 3) The three parts, 2B.stl, 3B.stl, and 4B.stl, have been replaced with a single part, 2_3_4_B_NEW.stl. Additionally, I've added two small accessories to facilitate the arm's adaptation to the Parallax S3 robot: S3_I2Arm_adapter_bottom.stl and S3_I2Arm_adapter_top.stl. Note that if you already have the original Lite Arm i2 base and want to adapt it for use with the S3 robot, you won't need to modify the base. Simply print the two adapters mentioned above.
