Experimental adjustable drive block for the Replicator 2X extruder. The purpose of this design is to allow the operator to fine-tune the pressure applied to the filament by the idler ball bearing.

Guess what it is!
Note: Gordbot guessed this way too fast, he definitely cheated, I'm just not sure how.
A very long solar filament that had been snaking around the Sun erupted today (Dec. 6, 2010) with a flourish. NASA's Solar Dynamics Observatory (SDO) caught the action in dramatic detail in extreme ultraviolet light of Helium. It had been almost a million km long ((about half a solar radius) and a prominent feature on the Sun visible over two weeks ago before it rotated out of view. Filaments are elongated clouds of cooler gases suspended above the Sun by magnetic forces. They are rather unstable and often break away from the Sun. Note: the edge of the moon can be glimpsed at 0300 UT during a brief lunar transit.
Since Dean and Jean recently posted filamentatous flowers, I thought I would jump on the stamenwagon and post one, too. This is a Golden Wings rose from Schoepfle Garden.

Inspired by (aka blatently copied from!) this shot I saw in explore. www.flickr.com/photos/kistomi/3197472752/ It is infinitely better lit than mine, but I think it came out not too bad :)
