Triforce Pendant (Remix) - Originally designed by Cowkitty.

thingiverse

I really liked this design by Cowkitty and wanted to make a way that the TriForce pieces could be removed and put back. When I tried editing the original file I found it had some extra geometry and wasn't perfectly symmetrical so I decided to take some measurements and rebuild it from scratch. I made the largest dimension of the outer most triangle equal to 50 meters. From there based all inner triangles on the mid point length between them. I included my Sketchup file from when I finished the Triforce piece, but before working on the hanger. I could never quite get the original hanger down, which I think was better than what I came up with. I created files for different sizes of the TriForce Pieces. I found that .95 scale was too loose, and .97 scale was loose for one piece, but snug for the other two, so I included a .96 scale piece which might be just right. lol. When too snug I just used my trusty Solidoodle spatula to remove it. It might be worth consideration to go looser and insert magnets in the frame and on the pieces. When scaling the TriForce pieces I only changed the Y and X axis, but kept original height. I figured having separate pieces allows the maker to color them as they please, and even print using different filaments. Possibly transparent or glow in the dark.
