Made this for the contest on Printables to challenge myself a little bit in modelling software :)
Check out my magnetic version and a 150% Scale derivative both accompanied by magnetic holders you can attach anywhere with double-sided tape. Available on printables through this link: https://www.printables.com/model/660015-simple-ice-scraper-with-optional-magnetic-holder/files
I want to say it works great for something I printed and was able to use on my car less than an hour later!
I always had problems with generic scrapers slipping out of my hands when the ice dust melts so these nicely filleted teeth make it very grippy and comfortable to hold even with a glove.
I'm open to any suggestions about the design and adjusting it to work better for you.
