== 3-D Modeling ==
 +
3-D modeling for this project was created with SketchUp 2017, along with some assistance through Thingiverse, where I found a customizable gear model. But even after modeling the gear through Thingiverse, it still needed cleaning up and re-configuring in SketchUp.

To get measurements, I used digital calipers. For the areas that were hard to measure or reach with calipers, I clicked out a length of mechanical pencil lead, then used the calipers to measure that lead.

== 3-D Printing ==
 +
It took me about 5 attempts to create the 3-D model. Each time, though, I learned from my mistakes and were able to start over faster. When I had a model that I liked, I exported the file to .STL format and imported that into Cura, which prepares the 3-D model for printing.
 +
 +
The first 3-D printout was a rough draft. I wanted to make sure the gear teeth would match up with the existing (broken) gear. The teeth matched well. But my biggest challenge was to make the spindle hole so it would fit on the pencil sharpener's spindle.
 +
 +
After tweaking the spindle hole, I was confident enough to make a higher-quality 3-D printout. As this part is not generally visible, I just went with what filament was already loaded in the 3-D printer.

== 3-D Printing ==
 +
After 3-D printing, there still needed to be some refining that had to be done manually. Cura added support structures to parts of the gear; otherwise, the printout would sag in places that needed to be kept straight. That support structure needed to be removed. Next, The spindle hole needed some minor shaving-down which I did with both a filing tool, and a little whittling with a utility knife. Furthermore, a few extra filaments between gear teeth needed to be filed down.
 +
 +
== Testing the Printed Gear ==
 +
Once I was able to fit the gear onto the spindle, it was time to test it out. First, I ran an "unplugged" test by manually turning the gear. So far, so good.
