UPDATE - 7/22/2017: Uploading V7 with blades that are 2 cm longer. Further updates, anything but the first two (V6 and V7), are available upon request. UPDATE - 7/19/2017: Watch this video on YouTube at https://youtu.be/5b0-aYOpFo8 Use This Tool At Your Own Risk! This is version 6 of my brush cutter, designed to attach to a Ryobi 18V String Trimmer. It's meant for cutting thicker brush in your yard and can handle large weeds about the size of an average adult male's pinky finger. However, I did break it when hitting a cedar fence, which isn't within its design parameters. Printing Tips I recommend printing this at 100% infill to achieve maximum rigidity. With moderate use, it should withstand wear and tear without breaking. To maintain sharpness, simply sand it down when needed. 100% infill adds significant strength to the design. Bonus Video: Check out Version 5 in action here https://youtu.be/4e7GXS0hwms, which definitely broke under stress. The version 6 brush cutter blades are twice as thick and tore through weeds with ease. Older Updates July 18, 2017: After several tests, I believe the design is sound but PLA filament isn't suitable for this tool. They all break after about 10 minutes of use. I'll be testing PETG and ABS filaments next and if they don't work out, I might try nylon filament. If you have any suggestions, please let me know.
