The file 'J-hook To Side-lock Wiper Blade For BMW X5 E70 And X3 F25 3D Printer Model' is (stl) file type, size is 6.0KB.
Thank you ruomserg. Made my day by allowing me to use $5 wiperblade arms instead of buying $40 ones each time.
Took it and flattened on the sides (also wider) and closed a little bit more the J hook part.
