I was going to buy and build one of these about a year ago.....totally waste of time....at least the ones you can buy....the items they produce are very poor quality....I thought they would have a flat appearance like original items but they are very rough and its just layers thin plastic on top of the other layer.....there are a few commercial designs I have seen that use a powdered resin mix and a laser that melts into the shape, those are awesome and they make actually working items.......but those aren't available on the public market yet.....we have a long ways to go before we can just go to Walmart.com and print out the items we want to buy.....besides the world will end as we know it by then......meteors are hitting the earth....earthquakes in Arizona today....strange weather...
