cults3d

Butterfly knife (balisong) having no blade but a pen instead . Composed of 6 parts, all printable without support : a mechanical pencil holder, to hold the pen 4 half handles, these hold clipped but can also be glued. a latch designed to hold with a piece of filament, do not hesitate to melt the end of the filament end to inflate its end and thus prevent it from escaping. The assembly is thus done without any screws. You just need to plan to cut a BIC® Cristal pen. To cut this pen, I took a grinder and deburred the inside with a 5.5 diameter drill bit, you should not be too abrupt on this step at the risk of splitting the pen. No worries about ink leaking when cutting the lead. F3D also provided to modify a dimension if needed. Link for the video here
