Step 1: Replicate the Curve of Your Ear
Using a cable tie measure the perimeter of the base of your ear by closing the cable tie until it fits snugly. It should not feel tight around you ear. Mark the top and the bottom of the cable tie in the area in front of your ear.
Step 2: Transfer Curve to a Vector Software
Place cable tie on a grid of with spacing of 1 x 1 cm and take a picture. Transfer picture to a vector software and scale the picture in reference to the 1x1 cm spaced grid lines. Trace the curve of the zip tie.
Step 3: Make the Shape of the Device
Add some thickness to the device and create an anchor where the rubber band will attach to. You may decide to place the anchor on either end of the curve. The rubber band should be able to wrap around the wire of the earphones and your anchor.
Step 4: Creating the Physical Device
You may create this device in several ways (e.g. 3D printing, laser cutting, manual cut). I chose to use a laser cutter with 3mm clear acrylic as the material because this will make the device sturdy but at the same time not noticeable when worn.
If you would like to skip directly to this step I have uploaded a SVG file with curve based on my own ear.
Step 5: Add the Rubber Band and Attach to Your Earphones
You may use any type of rubber band but the smaller circumference the better. If the rubber band is too big you may wrap the rubber band around the stem of the device till it is able to wrap around the anchor and earphone snugly.
