Balisong - functional but it should be metal

thingiverse

Human: functional with proper cleanup and fine-tuning. 100% infill. I used S3D's auto-supports, but made sure the separation was clean as possible. Drilled all pinholes with a 3/16 drill bit and gave it a little extra wobble on the pivot holes in the blade piece. Shaved imperfections off the pins to ensure proper fit. Glued pins to handles, but made extra sure both handles were free-swinging under gravity. Latch can go on either handle, but please put it on the correct one. Small round filed the whole thing and tuned the tang pin cups to work right. Like the title says, this was designed to be machined titanium and blade steel so the weight is balanced but extremely light. Flips pretty good when you find the right flick. The "spine bulge" is to improve chaplins. That's kinda the whole idea of this design.
