Practice Balisong/Butterfly knife Firefly MK3

The Firefly MK3 (Note the photos are of the Firefly MK2) How to print, how to put together, and how to use are all below. This is 100% printable. (My printer is a Creality Ender 3) The knife is five parts, each handle is different, and simple to print. You don't need to mirror anything or clone or print two of anything. It should be pretty self explanatory, but I know the pins are tight. I designed it that way. Pop 'em in with a hammer. Just tap, don't smash. Make sure your well aligned with the holes too. Firstly, no support is needed. I recommend 50% infill or more however. I know that's alot, but hear me out. The knife needs to be light. But plastic is far TOO light. So anything less that 50% infill will get you less than 1 ounce. I have tried doing Zen rollover, y2k, and half orbit using a 15% infill knife. They don't work. 50% is the lightest you can go for a semblance of realism. But I would recommend 100% infill. My best guess for a weight there (since I haven't tried that much yet.) would be about 1.5 ounces. Which is still far too light for anything super legit. So go buy yourself a cheap metal trainer to play with if your serious. This knife is designed to provide realistic play for tricks your already familiar with, without having to endanger your trainer blade. You don't have to care about this knife cuz you can print it out again if you break it. So this thing is essentially canon-fodder (For the pins I would recommend 15% infill. There are five pins because you should always have an extra. :) ) Alright so now that that's over with, lets move on. Special thanks to thing:2850822 your pins were the BOMB. Suffice to say this knife uses a modified version of your pins. I LOVE THEM. I, in fact, my entire knife was centered around making sure your pins fit in it. So thank you, for having the only good pins on thingiverse. I used FreeCAD to make the parts.
