This week we had to mold and cast something. Earlier in the week, I lost my airpods case somewhere in the Media Lab so I thought I would make an airpods case for this weeks assignment.
I have been using Fusion 360 this semester so I continued to use it for this assignment as well. My first approach to creating a tight fitting mold for my airpods was to model the airpods themselves. I looked through the internet to try to find a usable model with correct dimentions, however I wasn't able to find one, then I decided to model them myself.

Below I tried using an stl file of an airpods model already created. However, after importing the model in Fusion 360 and creating a mesh from it so I could tweak the dimensions of it, there were so many holes that I wouldn't be able to fix the mesh myself. I am trying to create my casing by having a model of airpods (that are slightly larger) created and just using the Combine tool to make a casing for them.
The first step is to find the dimensions of the airpods. The dimensions that I found from Apple are below. However, Apple didn't give a comprehensible list of all of the dimensions of airpods so I decided to use a set of calipers and find them out myself. The following are the dimensions provided by apple:
AirPods (each): 0.65 by 0.71 by 1.59 inches (16.5 by 18.0 by 40.5 mm)
Charging Case: 1.74 by 0.84 by 2.11 inches (44.3 by 21.3 by 53.5 mm)
These are the dimensions that I calculated. All of the following dimensions are in inches:
Diameter of the handle: 0.230
Vertical length of the handle: 1.083
Vertical Dip of the earbud from the top of the handle: 0.143
Horizontal Offset of the earbud from the top of the handle: 0.197 (back veiw)
Horizontal Offset of the earbud from handle:
(side veiw)
Vertical Length of the earbud: 0.627
Horizontal Length of the earbud: 0.64
Thickness of earbud from handle: 0.378
Length of speaker: 0.303
I found it really difficult to model airpods using Fusion, and will probably experiment with using Blender to make smoother curved lines and have more freedom with modeling using that platform. Also, throughout the week I also lost one of my airpods which made me not want to continue this project anymore. Therefore, I will finish molding and casting week by incorportating it in my final project.
