Improved handle for gravity knife fidget toy

I like the model I remixed quite a bit, but my handle gripped onto the base too tightly, and it couldn't open/close smoothly. I then reprinted it with some slight x/y compensation, and it worked, but the handle would come off of the body too easily. I made this remix just to make this model print more reliably for myself. 

Hope you enjoy!

I increased the space between the body and the handle by 0.1mm on each side, plus some additional distance in the outermost part (the part most likely to get stuck). This should prevent the parts from getting stuck together like some people had happen, and should otherwise make sure it's smooth. 

I also increased the length (and pointy-ness) of the hinges on the handle, by more than 0.3mm on each side. You'll now need to flex it very slightly to fit it on to the body, but I had no issues with my PLA print in that regard, and it now hinges very smoothly on that piece. 

Lastly, I rounded the corners near the pins on the blade. This should prevent the handle from ‘catching’ on them as you repeatedly deploy and retract this thing. I also separated the rest of the parts so that they could be printed individually a little easier.
