Testing Makelangelo pen holder v11

Victory? Victory!

In this version I changed the pen lifter. When the servo arm moved it would sometimes jam between the front and back lifter arms. Hot glue to the rescue!

Still a lot of testing to do before I feel really confident that it works, then update the BOM, get the pricing, and source parts from China. Now that I have a servo doing pen up and down I need a second power supply. Boo!
