I really like the tiny Flip Knife created from Y_Dascalu but somehow the pivot was a bit weak to hold & open the blade. I made a remix with following changes:
V2 Version uploaded with slightly bigger holes for easier assembling
It is mandatory to do some finish work after printing -you need a flat and rounded File to fit the parts together
Note: with the new thumb stud the blade goes not completely into the handles when closing-you need to make the slot slightly bigger with a round file
be careful-tiny parts!
print with slow printing speed
