This is what we saw while driving along the coast this week.


Elephant seals!


Lazy elephant seals. Don’t mess with them though–they grow up to 16 ft (5 m) in length!


Fear the mighty elephant seals! They make a sound like a backed up sink but even scarier.


This is how close we got to them.


And today we worked on the Z Stage of the Thing-O-Matic. This part has two self-aligning bearings for the two steel rods that allow the build platform to move up and down. At the top center you can see the threaded Z motor flange for the step motor.


This part was very easy to assemble but it took me over an hour because I thought the Z motor flange was missing. I double-checked and triple-checked all the parts bags and boxes before starting to write an email to MakerBot Industries. As I was writing the email I had to check on which model step motor we had and that’s when I discovered that they had screwed the flange on the motor’s threaded shaft. I guess that seems logical…now.

Tomorrow we begin working on the Stepstruder, which is the part that ‘draws’ the 3D objects.
