Just another simple Ice scraper. Print main part flat with PETG or PLA (other materials should also work fine). Print smaller part with TPU/Flex. Join two parts together and voilà - here is your frost scraper.

Also check my smaller remix of this scraper here.

Update 28.11.2023:

Today's weather allowed me to check how the scraper works. The TPU part works perfect but for the frost my scraper is a bit to elastic and bendy, so I decided to create thicker and stiffer version. The TPU part is the same for both version.
