Joe Larson

Joe Larson, known online as "the 3D Printing Professor," is one part artist, one part mathematician, one part teacher, and one part technologist. It all started in his youth, doing BASIC programming and low-resolution digital art on a Commodore 64. As technology progressed, so did Joe's dabbling, eventually taking him to 3D modeling while in high school and college, and he momentarily pursued a degree in computer animation. He abandoned that and instead became a math teacher, and then moved to software development for 10 years before returning to education, teaching technology in college. When Joe first heard about 3D printing, it took root in his mind, and he went back to dust off his 3D modeling skills. In 2012, he won a Makerbot Replicator 3D printer in the Tinkercad/Makerbot Chess Challenge, with a chess set that assembles into a robot. Since then, his designs on Thingiverse have been featured on Thingiverse, Gizmodo, Shapeways, Makezine, and other places. He currently produces weekly videos about design for 3D printing on his YouTube channel, http://www.youtube.com/user/mrjoesays.

Resizing the test ring

Now we are back to Blender to make a new test ring. This time, instead of starting from scratch, reload the project and resize the existing ring. Care has to be taken when resizing the ring to insure that it doesn't extend below the XY plane.

  1. Unhide the Finger cylinder by clicking on the eye icon in the Outliner on the line for the Finger object.

  2. Select All (A) objects.

  3. Begin the Scale (S) operation.

  4. Press Shift + Z to lock the scale operation to all but the z axis.

  5. Type 1.03 to scale the selected object just slightly larger.

  6. Press Enter to end the scale operation.

    Tip

    Pressing Shift and X, Y, or Z key when in an operation such as scale or grab, locks the operation to everything but the selected axis, regardless of view. With rotation, however, the effects are less predictable.

    Note

    The logic behind using 1.03 as a scaling factor is that past experimentation has proven this to be the right amount to overcome ABS shrinkage. It also coincidently brings the new ring very close...
