LED Robot Pop Up Card
Gella 
Step 6: Prepare Pop Up
Use a hobby knife to cut along the lines of the pop up template. Tape or glue a piece of vellum or a semi-transparent paper to the back of robot over the heart to diffuse the light from the RGB LED.
To pop the robot up from the page, first turn paper over to the front side (the heart should be on the right side of the robot). Carefully fold the robot's feet toward you.
Rotate the card so the robot's head is facing you and crease the top fold toward you and second fold away from you.
To finish the pop up, fold the card in half - making sure not to accidentally fold the legs. The robot should fold up neatly in the card.
To attach to your circuit, place the robot pop up page over the copper tape circuit and adjust as necessary so the LED shines through the robot's heart. Trim edges if needed and use glue or tape to fix the corners down. Be careful not to glue under the pop up pieces or they may stick down when closed.
