Wood Handled Ice Scraper

A Canadian staple! You'll definitely need one of these if you are planning on driving in the Winter in Canada, or most Northern climates.

I designed this scraper to be more robust than the store bought ones. I also tried to minimize plastic by using a wooden handle, which also means that you can customize the shape and length of the handle to your liking! It is designed to mount to an 18mm x 25mm piece of wood, if this design is popular I will also make an imperial variation. The handle is screwed into place using two short wood screws.

I've modeled in supports, basically to help it stick to the bed and ensure that there isn't any wiggling, they will be more efficient than auto-generated supports. If you would like a version without them let me know and I will upload it.

This is the first version and they haven't had much testing yet. I would love any feedback so that I can improve the design and hopefully one day turn it into an actual product that reduces the annoyance of regular ice scrapers for many more people! If you test it in other plastics and find that something else works better than ABS, that information would be much appreciated.

Print instructions

Printer Brand: Prusa

Printer: I3 MK3S

Rafts: No

Supports: No

Resolution: .3mm

Infill: 20%

I printed with 2.5mm thick walls to ensure that this will be a very sturdy part as it will have to stand up to a lot. I also made sure that the top 5mm was printing solid to give the edge an extra advantage.

I used a 4mm brim to help make sure that the print stuck down, it snapped away easily with the modeled supports, and I heated the plastic to remove the white marks where it was removed.

I've included my gcode, it prints with the standard 0.4mm nozzle but varies the flow on the internal perimeters to get material down faster!

Post-Printing

After printing, remove the supports and find two short wood screws. I used Robertson (square drive) screws because they are nice and sturdy, and another Canadian invention! I found that it is easier to screw in the screw closer to the end first to ensure that the other screw doesn't block its hole, you may also need to clean up or open up the holes a bit more depending on the size of the heads of the screws you use.

I used 18mm thick plywood and shaped the end to fit inside of the scraper head. I used teak oil to give it some waterproofing and a nicer feel.

How I Designed This

I used Rhino 6 to model this
