A really simple print to fit pretty much any printer that will keep the ice off your hand while you clear your windscreen of ice.

Orientated to print on it's side, which I think will be the strongest way to do it, but if you know you can manage overhangs better than 65 degrees it will print fine flat against the bed.

Not tested this out in anger yet, just waiting for the first frost of the year.

Update 29/11 First snow of the year and I'm happy to confirm it works as intended.
