Summaryeasy to print shredder. is remix of my easy shred v4. what is the same is the box and the handle and the handle grip. all else is changed to make it easier to print. whereas v4 is easier to assemble. if you printed the v4 then you can use the same box, handle and grip. there is one file for the cutters cuz you need to print 9 of the same. one gear fiile cuz you print two. there is a spacer for place between handle and gear. you could replace the plastic cutters and shaft with metal ones. but would hav to b specially machined to fit. just sayin.
