I’ve just take the first step to building my MakerBot!  Admittedly, two of the bearings were already in the printed pulleys, but that’s just not the point.  I’ve taken a material step towards building it!  Huzzah!

Printed pulleys assembled!

Oh, and I don’t think I was supposed to have a pack of 8 extra bearings.

No, no, I’m supposed to have these 8 bearings.  I suppose it would help if I read the directions.  (I’m just so used to grabbing things and tossing them together and expecting them to work.  I guess it’s a little more complicated than that when you’re building a robot, eh?)
