Grass Trimmer Part

My grass trimmer has a third party head attachment fitted. I much prefer this head to the original spool tap approach. I often found that the filament broke at the spool opening, which meant opening the spool to rethread before I could continue with my lawn duties.

After 2 years, one of the filament holders on the third party head broke. This broken part is not available as a spare part, so it was either buy a whole new head or 3D print a new holder. Here is my 3D replacement part.

I used PETG filament to make the part. I found that an exact size part copy was not durable in PETG and soon broke. My part version has been strengthened by increasing some of the dimensions and with some subtle design improvements appears to make the part more resilient. Fortunately the 3D part is cheap and easy to replace, so should the other holders break, too, I can replace them, too.

I hope that you can find this print useful, too.

Remember to leave me some feedback or even a tip to keep me enthused to make more of these drawings.

Print instructions

My print is made in PETG 1.75mm 3DFillies black filament, with 0.2mm layer height and 100% infill on a PRUSA I3 MK3S printer.
