Ice scraper protective cover

I really enjoy my [Murska Ice Scraper](https://pvb.pp.ru/b.php?item=icescraper) while removing ice and icy snow from my car windows. The only deficiency is that its metal blade is rather sharp and has no cover. I almost cut my hand once picking it up.

So I decided to add a little safety precaution and made this protective cover.

If you have the same ice scraper (metal blade width = 89mm, metal blade thickness = 0.4mm), you can print the model right away. If your ice scraper has a similar, but different metal blade size, please use FreeCAD to open IceScraperCover.FCStd and adjust the sizes in "s" spreadsheet to your use case. Please refer to https://wiki.freecadweb.org/Spreadsheet_Workbench

Good luck and a safe use of your ice scrapers.
