UPDATE: 4/1/2024
V2
has thicker center where the line is wrapped i found that mine broke there and was a weak spot also added a 3mm hole 10mm deep for adding a screw for longevity and ware resistance
V1
is the same as the original accept the bump sticks out further
made a replacement bump feed for makita DUR193 line trimmer because i was told by a local makita dealer that you cant buy replacement ones id recommend printing at 100% infill and out of something tough like petg i made mine in pla, i might make an updated version where you can add a screw to the head as a ware plate to save the plastic and make it last a bit longer. the holes where the line go depending on your printer might need to be drilled out
