Simple Blank Warning Triangle (200mm sides)

I needed some high-visibility warning triangles for tying to a temporary fence. Not a complicated design - but very useful when the need arises.This simple sign has 5mm holes in corners for string, wire, or any other form of attachment you can think of. It should be relatively easy to modify this model to take magnets instead of being tied on.I printed mine out on High Vis Orange PETG for outdoor use.
