Upgrading a trimmer with 3D printed parts

Many have complained about the difficulty of rewinding their weeders with fresh trimmer line. Manufacturers responded by making models with solid plastic blades instead. Some of them suck, though, like this Ozito model from [Random Sequence]. 3D printing was the way to go, adapting the blade trimmer to use the traditional line.

The design is simple. [Random Sequence] created a small plastic tab that matches the plastic blade attachment tab of the Ozito trimmer. At the end of the tongue, instead of a blade, there is a round slot into which a length of cutting wire can be inserted. The trick is to use a cigarette lighter to lightly melt a bulb on a length of cut wire so it doesn't go through the slot. Centrifugal force (discuss in the comments) keeps the line from falling.

[Random Sequence] prints these in PETG, but note that the part could use some extra strength. They break when hitting hard objects, much like the original cutting blades do. Also, unlike a bump trimmer head, there is no way to automatically feed more line. Instead, just manually assemble several tab adapters with a new line.

Overall, though, it's a great way to adapt a stronger, more capable trimmer line to an otherwise crippled weedkiller with weak blades. It is reported to work with Ozito and potentially Bosch tirmmers, and the parts are on Thingiverse for those who wish to print their own.

Just like the brushcutter line was once used as 3D printing filament, you can also go the other way, by turning old plastic bottles into a brushcutter line. If you've cooked up your own fun garden tool hacks, please let us know.

Also say your best name for a weed killer in the comments. The Aussies may hold the title with 'Whipper Snipper', but we're open to other entries!
