Triforce

I wasn't much of a fan of any of the Triforces I saw here, so I made my own! I used FreeCAD to design the files. You can't see in the pictures, but the tapers are on the other side as well, so it can stand balanced.

I had the best luck printing this upright, but you can definitely print it lying down.

When printing, I used a small horizontal expansion of about .3mm to make sure that the pieces actually connect, since in the files the corners are just touching. Otherwise, it'll be much too fragile and won't print in a single piece (at least on my Ender 3v2).
