GreenWorks 40V String Trimmer Bump Knob Replacement Weed Wacker

thingiverse

This STL is for a replacement bump knob for the larger GreenWorks 40V string trimmers, like model: ST40L412This knob features alignment markings for winding more string and direction arrows for winding.Note the print setting recommendations for optimal longevity of this print. Supports aren't needed if printed with flat side down (like a cup) and you can make sure all the overhang is printed as "additional perimiters." My PrusaSlicer prints the overhang with no supports when this feature is ticked.Also note this STL is sized for PETG which shrinks more than PLA after printing. For PLA prints (more brittle/less durable), try scaling this down 0.5%-1%If you want to support me by buying the finished knob directly from me, head over to this eBay listing: https://www.ebay.com/itm/256250720306
