One of the most popular soundtracks of the year has to be the Awesome Mix Vol 1. from Guardians of the Galaxy. The songs on the soundtrack figure prominently into the film since they’re on a cassette tape that once belonged to Peter Quill’s mom. Instructables user msb87 came up with a wearable version of the cassette tape made from cardboard, tape, adhesive, paint, and paper. It’s a clever idea, and I hope to see more than a couple people tackle this during the next convention season.
The first step involved planning and msb87 used an actual cassette tape to get proper measurements and proportions. The design was transferred to a two-part sandwich board style cardboard costume that’s worn over the shoulders.
Msb87’s notes on assembly:
Marking Out: Using the plan we just made mark it out on the inside of each piece of cardboard. On a separate piece of cardboard mark out the toothed wheels (My dimensions used saved as notes in diagram). Don’t worry about being perfect as at this scale people won’t be able to tell.
Cutting Out: Then using the craft knife and cutting mat carefully cut out the small circles (Red) and the 2 big middle circles (Blue) for both pieces of cardboard. Keep the 2 big circle cut outs for later. Do the same for the toothed wheels.
Then cut along the line Green line to separate the trapezoid shaped section from the main body. Cut 3 strips of card to go round the top and side of the trapezoid.
Assembly: Attach the strips to the trapezoid making sure to use masking tape on the outside. In my costume I raised the trapezoid by 20mm and then folded the excess flush to the inside of the main body and secured it using Packing Tape.
Finally cut 8 cardboard squares and stick them to the inside of each corner. This creates the recessed screw holes.
