About this 3D model

I am attempting a 3D Printed circuit. I painted this model with conductive glue and I used a wire to attach a CR2032 battery. Many ATTINY chips can be programing using the Arduino IDE. See http://www.arduino.cc/ http://highlowtech.org/?p=1695 Use Arduino as ISP or In Circuit Programmer. I tried Makergeeks conductive ABS but is has high resistance so a conductive paint or paste had to be used. Attiny84 Datasheet: http://www.atmel.com/Images/doc8006.pdf At 3V resistors are not really needed to limit current for LED. I tried to use SMT led but I could not get a good connection. Just learning AutoCAD Inventor and this is my first project. Hopefully more to follow.
