mbotplate5 from Prusa Mendel
Test print using early reversal in the new, experimental reversal plugin to Skeinforge.
This is uncleaned - printed for reference.
Printed on a Thing-o-matic with a stepper extruder.

Mendel Belt Splitter Jig 2
Inspired by the belt splitter from Ed, we quickly designed and lasercut this one.

With stanley knife inserted.
Mounted in a vice, this doesn't even require wearing leather gloves :)

Arduino CNC controller
Closeup of our old Arduino CNC controller setup. The Arduino output signals corresponding to what the CNC software outputs on the PC parallel port. We then simple route these signals into a parallel port connector.

Temporarily attached CPU fan
Since the Makerbot prints significantly faster than our old CNC-based reprap setup and the firmware already has a command for turning cooling on and off (on=M106, off=M107), I taped on an old CPU fan to see if build quality improved.
Nophead's utility meter key with and without cooling
Build quality improvement by adding cooling.
The left object was printed with the default Makerbot setup (i.e. default layer size, feedrates, filament feed etc.) with no cooling.
The right one uses the exact same parameters, but with the cooling fan running during the entire print.
I was really amazed by the difference - I guess this setup will be permanent from now on :)

Kali - second print
Parameters tuned and our first test object came out quite nicely. Had to switch to black ABS for the occasion.
Kali - first print
Something went wrong with Skeinforge combined with wrong machines.xml settings for the V2.3 stepper motor drivers.
Makerbot #43 in progress
Twisted boxes in production
Zach went into mass production of twisted boxes as a giveaway for Maker Faire. The combination of black and white looks awesome.
Reprap Action Car @ Noisebridge
We donated our reprapped action car to C-Base for their fund raising auction during 25c3. We had no idea who actually bought it until we stumbled across it sitting in a showcase at Noisebridge when Philipp and I visited them in SF.

Nice :)
