I ran out of blades for my weed eater and I was about to head to home depor and grab some, but it struck me...I CAN PRINT THAT! made in tinkercad using the original blade as a base and took some liberties with my take on what would work well for cutting grass. printed in PET at 100% infill. my test blade fit perfect and lasted a good while before I hit the house and sheared it off. it was only 20% infill though. I am thinking 100% can get me through a yard. Will update next weekend when I have to mow again :D Just to be safe - do this at your own risk. completely untested and I don't exactly think stuff through all the way before I do it. Mainly an exercise to see if i could do it. First results are in...as a proof of concept it works. not very practical and definitely not safe. fun to play with though. I may try some other designs that may be more sturdy https://www.youtube.com/watch?v=uXjaNJJvpWw http://imgur.com/VR4UNVf
