The 'Open Source Universal 3D Printer Extruder' campaign, began by Chelsea Thompson, is described as "A universal, 100% open source plastic extruder" for a variety of 3D printers.
Manufactured with a single or dual extruder, the developing team hopes that adoption of the new hardware will lower the price of 3D printers worldwide -- making it easier for the average consumer to get their hands on one. The 3D extruder was created by taking Makerbot's open-source design and trying to improve reliability by "replacing the hobbed gear with a 20 tooth spur gear (ala Makergear) with a groove machined into it which centers the filament along the axis of movement", and changing the plunger -- ultimately also cutting manufacturing costs.
The project's Kickstarter campaign managed to secure $73,361 based on a $5,000 goal.
