Folding Knife

This is my first actual modeling project, so it's probably far from perfect, but I got it to a point that I'm happy enough with.

I wouldn't recommend using it as an actual knife. I tried to stab a box and the knife fell apart. Granted, I printed in PLA and stronger materials might hold up better. The knife is still fun to play with, but be careful of the tip; it can still hurt you. Might be a good idea to round it off if you're looking for a toy.

Problems that need further engineering:
- PLA locksprings do not last. Leaving the knife closed for minutes at a time can bend the spring out of place so it doesn't hold the blade anymore. I plan to test out new locking mechanisms later.
- The pins may need to be resized depending on your setup. The pins are currently 3.9 mm going into a 4.0 mm hole, and may be better for you with 3.8 or 4.0 mm pins. The pin near the blade especially needs a tight fit.
- I tried to design this so it wouldn't need to be glued together at all
