Folding Knife Letter Opener (easier print)

thingiverse

Yet another model stops by the doctor... This is a remix of [budgiesarecool](https://www.thingiverse.com/budgiesarecool)'s letter opener in the shape of a pocket knife, with these minor improvements to make printing easier: * Finally the correct scale (why everyone kept the wrong scale in their remixes, beats me…) * Manifold models (thanks to [MasonIsLegit](https://www.thingiverse.com/MasonIsLegit)) * Everything is positioned for optimal printing. * The pin and hole are 4 mm in diameter. This makes it easier to ream the hole with a 4 mm drill if needed. * Two variations on the pin, one narrower and one fatter, so you can pick the one that fits best (tip: print all three at once, this will avoid melted filament blobs). * A variation on the handle with less steep overhang, making it easier to print without supports or cooling issues. * Slightly tighter tolerances, for a smoother finish. * I've also added an alternative blade with serrated edges, better suited for cutting thicker paper. And to the person asking this question: yes, it will probably cut through cardboard if you print it with hard enough filament!
