Line release button for Morrison BC260 line trimmer.
The part is not being sold separately, the closest part number is the full trimmer head assy. I did not want to order that, but without the middle button bit there is no line release during operation which is very inconvenient. Measured the remnants of the original bit and here is my take.
Solid part (100% infill on all layers) print time is cca. 3hrs, PLA.
