Introducing the BlueFlux, a butterfly knife trainer for the safety-conscious and the style-savvy. It's a 3D-printed nod to the classic balisong, minus any sharp edges, because the only thing we're cutting here is the tension with a little humor.
Design Digest:
The handle's got cutouts that aren't just for show – they keep things light enough to make you forget you're holding anything at all. The blade? It's as blunt as a toddler's honesty and features a nifty transparent inlay for those who appreciate a bit of flair in their flip.
Assembly:
Filament: I recommend using PLA for the handle for its vibrant color options and a metallic filament for the blade to get that shiny contrast. Bill of Materials: 2 x 3mm screws (12mm length) 2 x 3mm nuts (for a snug fit) Screw it all together, and voilà, you've got a trainer that's ready to flip, minus the trip to the emergency room.
Printing Advice:
If your printer is MMU-capable, grab the provided 3mf file for a seamless print with the blade insert. For single-extruder printers, use the 'blade-singlecolor.stl' file. You can still achieve the visual effect with a filament swap at the right layer. Recommended layer height is 0.2mm, and you won't need supports. If the first layer is playing hard to get with the bed, a brim might help.
Happy printing and flipping, and remember – in the world of balisongs, style is just as important as skill!
PS: Also provided the Blade in a alternate orientation. To be honest I'm not sure what is the most cool looking, so I provided both. They are marked with -alt in the filename. Enjoy.
