I made this for the head lights on my car, LED lights don’t produce as much heat as traditional light bulbs so moisture tend to not evaporate and ice doesn’t melt very quickly.

I printed the handle with PETG and the blade with TPU 95A, if you are to have any chance of removing ice you want to use a TPU that’s not too soft.

I made three different styles of the blade, try them to see what fits your needs and expectations.

Depending on how well your printer handles bridging the blades can be too short or too long, if they are too long it’s easy to cut them with a razor blade and if they are too short you can make them longer in your slicer, just make sure you only enlarge them in one direction.

If printed as oriented in the stl file you shouldn’t need any supports, and make sure you print hot enough (or doesn't use too much cooling, which in effect is the same thing) so the layers adhere properly, it is very important when you print a small and tall model like this.
