You should check out my print in place version: https://www.printables.com/model/1215608-print-in-place-gravity-knife-v1
Due to its popularity on printables(There is already several remixes). I feel I should Reopload my gravity knife from Thingiverse here As well……
Carrot Gravity Toy Knife Generation 2 Was great, but had some real Issues with the file Names messing up the download. And I didn't like having to glue it together. So I have modified it and re uploaded it. But in the time I was working on it, I can't find the original file
UPDATE: the creator reached out to me. in the comments And here is the link to the originals:

Also, if you have a tap and die set and you want to clean up the threads, I used. M5X0.8 for the small one. And M7X1.0 for the big ones.
UPDATE: I added some looser tolerance files I shrunk the blade by point 2 millimeters in each direction and the outer edge of the pins. So hopefully the blade moves smoother.
Note, if your printer is capable of making the pins in the handle. and you print the updated ones. The handle won't flip open properly. It'll jam each time because it is fairly tight tolerant so only. print those if your printer fails at the other ones.
Because of the threads, it's highly recommended to use the best resolution you can. I have found it works with layer heights of 0.15 and 0.1 Pretty good.
I printed using Army Green PETG. but I wouldn't recommend PETG Unless you have your printer really dialed for it because you need it to be a pretty good resolution. And PETG has surface finish issues that might need some sanding
Also, when assembling. the bolts/pins. will screw in better on their respective side So if it isn't fitting smoothly, try the other bolt. It's kind of hard to say which one is supposed to be for which side until you try.
