weed eater blade

this is a replacement blade for grass/weed trimmers. Its a basic but effective design that fits any weed trimmer that takes plastic blades with a 7mm notch. Ive been making these blades for a long time never had a problem other then the normal wear and tear you get from the regular blades. Ive found they work excellent with regular modeling resin because of its flexibility although I haven't experimented with any other tougher resins and im sure you could find a material that's a little more durable and get a little more life out of the blades but the goal here is to save money and it wouldn't be very efficient printing your own blades if your using expensive resin. I print them face down flat on surface and there's a notch on the back to make them easier to peel from platform.
