Functional Attack on Titan Sword V2 (read description before printing!)

thingiverse

This is my own design of a life-size Attack on Titan sword replica, and I'm really proud of how it turned out. The detachable blade is held firmly in place by a strong magnet lock that works perfectly every time. While I'm happy with this version, I know there's always room for improvement, so you can bet this won't be my last attempt at making one. To make one yourself, start by printing five of the Blade mid.STL files and one of all the other necessary parts. You'll also need a 4x785mm threaded steel rod (the blade core), a 4x36mm (threaded) rod (the lever axle), and two 5x5mm neodymium disc magnets like these https://www.supermagnete.nl/eng/disc-magnets-neodymium/disc-magnet-diameter-5mm-height-5mm-neodymium-n45-nickel-plated_S-05-05-N. Keep in mind that if you scale this design up or down, the metal parts might not fit perfectly. To assemble the blade, screw the middle segments onto the core, then attach the base and finally slide on the top piece. To put the grip together, install a magnet into one of the halves before gluing them together. Then, place another magnet in the blocker's pocket, making sure they face outwards so they can repel each other. Slide the blocker into its slot with the thin side facing the blade, then attach the lever. If your magnet lock isn't working smoothly, try sanding down the contact surfaces of the moving parts.
