Dụng Cụ Cạp Băng Chịu Lực "Heavy-Duty"

A Heavy-Duty ice scraper.

This model is designed to be printed with the blue highlighted face on the build plate to put all of the force of the scraping into the layer lines instead of across them.  This should help tremendously with part strength. Print from ABS or ASA with 30/50% infill for the best strength with 3-5 walls. .6mm Nozzle recommended. 

Post processing may require you to sand the adjacent edge that contacts the window flat depending on your print quality.
