This SmartRap is a redesign of the printer designed by smartfriendz. I've made improvements on the z accuracy and all together reliability of the original, yet still keeping budget in mind. I redesigned this SmartRap so it would be the easiest RepRap to assemble and one of the most mobile printers while still keeping a large build plate. All but 6 of the parts are redesigned.If you want to show your support, I sell kits, all parts sourced from the USA, ready to assemble on eBay here: http://www.ebay.com/itm/291551182781?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649 . Kits are made to have parts of the highest quality, while keeping a very low affordable price.
