-We cut this design in the vinyl cutter, the outer part twice in heat transfer vinyl, and the inner part once in baking paper. After cutting, we layered the vinyl pieces on top of each other with the baking paper in the middle. We then used the heat press (temperature 110 degrees, 15 seconds) to seal the vinyl pieces together, leaving the baking paper part unsealed - thereby forming the air channel.

 I used the design shown in the presentation to create a mould in Fusion 360 that had rounded corners at the centre and pointier ends on the arms. I thought that the rounded corners might make it easier to remove from the mould and decrease the likelihood of tearing. I then 3D printed the mould using normal PLA. I used the design shown in the presentation to create a mould in Fusion 360 that had rounded corners at the centre and pointier ends on the arms.
