Project Overview: 3D Printed Replacement Blades for Ryobi 40V Trimmer

Background:
While clearing thick, tall grass and weeds on a wooded property, I initially used the Ryobi 40V trimmer with the included trimming line. However, the line proved ineffective against the dense vegetation. I then switched to the plastic blade head attachment that came with the trimmer. The blades performed well on grass and weeds but were highly susceptible to damage when they came into contact with rocks or hard surfaces.

I purchased a replacement pack of 8 blades from Home Depot for approximately $20 after tax. Although effective, the blades wore out quickly, and I exhausted the pack in a short time. The cost of continually replacing these blades was not sustainable.

Solution:
To reduce costs, I explored 3D printing as an alternative. I searched for existing Ryobi-compatible blade models but found the available options either incompatible or poorly designed. As a result, I decided to design my own blades for 3D printing.

Testing and Results:
I printed the blades using PLA filament and tested them with the Ryobi trimmer. The printed blades performed comparably to the original Ryobi blades. Like the originals, they began to show wear upon contact with stones and hard surfaces. However, given the ease and low cost of reprinting, this was a minor issue.

Cost Comparison:

Official Ryobi blades: $20 for 8 blades → $2.50 per blade

3D printed blades (PLA): Approx. $0.29 per blade (based on Prusa Slicer estimates; actual cost may vary depending on print settings)

This represents a significant cost saving, making 3D printing a more economical and sustainable option.
