Do i need to scale one down a percent or two to get them to fit? how good did yours fit after printing two identical ?

You can't fix that by scaling, because the parts are symmetrical and interlock. You'd have to scale part of it to adjust the fit. Probably easier to change the arrowhead than the cavity. Even then, they'd need to be printed both the same.

Right. The arrowhead is already scaled down vertically by about 10% after inverting it from the cavity, but it's still a really tight fit, especially because the arrowhead can be a little unfinished printing on supports.

Doesn't matter anyways, as you can see by the makes, i printed out, and it works perfectly without any changes, Granted my printers can easily get away with 0.1 parts tolerance, might not work so well on other printers.
