GM to Trico wiper blade adapter
thingiverse
The tabs that hold the wiper on the arm are always breaking. Typically the blades are still good but there is no way to get new attachment adapters except with new ($40+) blades .. unless you have a 3D printer!!! I used the cheapest PETG I had on hand (happened to be orange) at 0.3mm resolution and it took 3 tries to get the geometry perfect but it now fits better than the OEM version and shows no sign of being fragile. Not sure if/when I'll get around to printing in black ASA or something similarly durable in weather. Perhaps if/when this one breaks.
