For this project I used Tinker Cad. I decided to use an accelerometer in a game controller. Before starting I went online and found that the dimensions of the accelerometer were 20mm by 20mm. These served as my guidelines later for creating a slot for the accelerometer.

After obtaining these dimensions, I went into Tinker Cad and using the Playstation Move controller as a reference, started modeling. First, I made a handle with a diameter of a little over two inches (I found that this would probably be comfortable to hold). Because I didn’t want to copy the Playstation Move exactly, I made the ball on the top significantly larger. This would provide for an interesting weight distribution on the controller which could more easily simulate what you would feel when holding something like a tennis racket which is more top-heavy.

Then it was time to work on creating the slot for the accelerometer. To start, I put a base box which would make a smoother plane to cut into (I didn’t want to cut the slot directly into the cylindrical handle). After that, I used another box with the dimensions of the accelerometer and cut that shape into the handle using the “hole” function.  I also grouped all these shapes together to make them easy to work with.

Lastly, I decided to brand the controller so I created text with the words “Magic Wand” and grouped them on to the controller.

This was an interesting project because, although I had 3D modeled before, I had never given much though to the real-world dimensions of the product I was creating. Tinker Cad made it really easy to change these dimensions and make them actually useable. It was also a very easy program to use compared to the previous ones I had been exposed to (Blender and Meshmixer).
