You can make a your own 3-D glasses frame with cardboard. You need some cardboard, scissors and 3-D glasses(only the lens).
Step 1: Cut Out the Cardboard
Cut a 6 inch by 2 inch cardboard( cut it to the shape you want) and trace the lens on to the cardboard and cut it out
Step 2: Putting on the Lens
push the lens from the glasses and tape them on to the frames.
Step 3: Making the Ear Piece and Completing It
DEPENDS ON HOW YOU WANT IT. I cut it 5 inches and same thing to the shape you want. Then just tape it to the sides of the frame and your done.
