Working with an Objet printer is fantastic, however unless you live in Israel you'll probably never be able to find/buy Zico replacement blades. As such we've created this replacement Objet Pedestal Scraper / Window & Tile Scraper which is designed to fit any box cutter blades. The STL is set for blades of 0.5mm in thickness, however if your blades are thicker or thinner, simply scale Z accordingly. Scale factor = 2 * "Your blades thickness in mm" You can learn more about this thing on our blog http://prototype.asia/blog/2013/05/02/mastering-your-objet-replacement-pedestal-scraper/ It can also be purchased on Shapeways : http://www.shapeways.com/shops/PrototypeAsia
