18V Ryobi Line Trimmer Double Spool Modification

Ryobi 18V Line Trimmer Double-Line Spool

Tired of your Ryobi One+ 18V line trimmer having only a single cutting line? This upgraded spool is a simple remix of the original replacement spool, modified to wind two lines, effectively doubling your cutting power!

Features & Notes:

• Double-line upgrade: Increases efficiency and cutting performance.
• Easy adjustment: I drilled a single 3mm hole directly opposite the existing one - this doesn’t affect normal function and can be left in place if you swap between single- and double-line spools.
• Compatible line: Use 2mm replacement line from Bunnings.
• Printed in PETG: Requires supports; just glue the separate parts together (I used Loctite 454). Support interface may not be perfectly tidy, but it’s sturdy and functional.
• Use with caution: I removed my guard, as many do - any modifications are at your own risk. I’m pretty sure Ryobi doesn’t recommend this. 

Get more out of your Ryobi trimmer with minimal effort and a simple, effective tweak!
