This is a device that you can make to light up the inside of your MakerBot. By using some LEDs, a couple resistors and the MakerBot power supply, you can give your MakerBot that cool glowing interior. It is designed to snap into the slots on the top of the MakerBot, and be wired to the 12V line of the MakerBot power supply using unused HDD connectors. It is easy to print up a pair and give it a try!

This is a conical pulley that can be used to operate a "Prop Dropper" type animatronic feature. The details on the construction can be found in teh October 2009 Nuts & Volts magazine ( nutsvolts.com/index.php?/magazine/article/the_halloween_prop_dropper ) This one is designed to attach directly to a Solarbotics GM-3 gearmotor. It is a tight press-fit as printed, and stayed well-attached without the need for any adhesive.

This is a very little (20mm^2) box, with a matching lid. It prints quickly on a MakerBot or RepRap, and the lid fits snugly. It is perfect for carrying very small things, like one marble... It is a great little demo print to show off your fabricator to impatient friends.
