Two-armed Puller for Wiper Arms

grabcad

This device, designed for most passenger cars, helps pull off wiper arms effortlessly. The original product features die-casted parts in traverse and puller arms. As an accurate replica of the existing device, it's available on www.amazon.de at a price of 47.49€, which I believe is too high. Consequently, I modeled it for CNC manufacturing. The 3D model can be accessed in various formats, including STEP (.stp) and PTC Creo Parametric (.prt and .asm). Note that thread dimensions are theoretical, without clearance, while a hardened ball bearing with a 4mm diameter is pressed into the spindle. The O-ring secures the brass pressure piece in an axial direction. If you're interested in making your own device, please like before downloading. I aim to help those facing similar wiper arm issues, while also acknowledging the original product's usefulness without endorsing it. Thank you for reading!
