I have been printing more (after work).  I updated the MakerWare Version 1.1.0 (http://www.makerbot.com/makerware/) and the MakerBot to firmware 7.0.  The firmware has an updated slicing engine which my first impressions it appears be over all more efficient as they claim.  It is certianly much faster at slicing.  I did not time how long it took before but now its almost instant.  Previous to this release the printer for swing back and forth between multiple objects on the when printing.  Now it will stay on one object and print an entire layer of the object before moving on to print and entire layer on the other object.  It does seem to print a bit slower on the outer layers of the objects.  I am not sure that I can recall if it did this with the previous layers or not.  I would assume that it is printing in finer detail on the outter layers so this is definately a good thing.

Here are some more things that I have printed:

Raspberry pi case 1h 35min (http://www.thingiverse.com/thing:24945).  I decided to change filiment color this is called Icicle Blue http://store.makerbot.com/filament#pla. It warped away from the build platform for some reason. But it turned out ok anyway. Not sure if it was the new filament that did not stick quite as well or what. More printing with this filament might reveal the answer.

Tweezers http://www.thingiverse.com/thing:25587 and Nautilus Gears http://www.thingiverse.com/thing:27233. I printed some mechanical things to see how the printer does. The Tweezers work well. The points don’t quite stay lined up as well as I would like though but are useful for soldering SMDs. The gears work just ok they don’t really snap together as well as I would like but I am sure that a dab of glue will solve the problem to hold them together better.

Plastic Spring thing http://www.thingiverse.com/thing:39963.  Wanted to see what happens when the printer needed to bridge a gap with plastic. You can see that the outer edges have plastic that spans a good 3/8 inch. The detail is lost in my crummy
photos but you can see that it did impressively well spanning with no support.
