Balisong / butterfly knife - weighted and very nice

thingiverse

This balisong is a very nice and smooth one, requiring M4 screws all around. Ensure that you use locking nuts for added security. At the base of each handle, insert a screw followed by two normal nuts, finishing it off with a locking nut (one nut should be positioned inside the handle, which is why the M4 nut design exists). This will result in nicely weighted handles. This model features a printed center pin on the blade, mimicking the behavior of a real balisong. The performance will be impressive! To achieve smooth handles, print them flat on the bed with the holes facing upwards and use supports between the handle sections. This approach ensures that the holes are nice and smooth (the inside texture is not important since it won't be visible). The printing settings used were 0.2mm layer height and 60% infill to create a strong product. Check out this model in action: https://www.youtube.com/watch?v=FOcKPevliAE
