Modeling the finger

Now that all the measurements have been taken, it is time to go to Blender. Start a new scene; (De)select All (A) objects and Delete (X) them. Then save the scene (Ctrl + S) in a new directory under the Makerbot Blueprints directory called Ch4 SD Card Ring and name the project file as SD Card Ring.

1. Add (Shift + A) a cylinder. In the side bar to the left, change the options for the cylinder. Change the value of Vertices to 64 so the cylinder is smoother than default. Change the value of Radius to half the diameter of the measured finger. Change the value of Depth to 10:

   

   Note

   Blender can take simple equations in these boxes, so instead of dividing the diameter in half to get the radius, simply type the diameter followed by /2 and it will divide it by 2 for you. So, in the preceding example, typing 19.3/2 resulted in the value of Radius being shown.

2. Select the Object tab (orange cube) from the properties on the side bar to the right, rename this cylinder to Finger as this cylinder...
