Hyperboloid
George Hart's hyperboloid.
Printed on a Thing-o-matic with a stepper extruder and the reversal plugin to Skeingforge with default parameters.
This has not been cleaned. Printed for reference.

Plastruder Mk5 alternative resistor mount
Hot soldering the wires to the resistors was messy. I think this alternative approach is a better solution. Use M2 screws and nuts, and a star washer to get a better grip on the wire.

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 the Makerbot #1
Kali the Makerbot #2
Kali - second print
Parameters tuned and our first test object came out quite nicely. Had to switch to black ABS for the occasion.

Something went wrong with Skeinforge combined with wrong machines.xml settings for the V2.3 stepper motor drivers.

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.

New Makerbot X-Y carriage with old McWire carriage #2
The young are so bright and shiny, but the old one built from stainless steel and aluminum just chuckles at how brittle the young ones are today.

First extrusion!
After hours of debugging, culminating in finding an invisible solder bridge on the avr chip, we finally reached extrusion on our first extruder. The second one is being built as we speak.
