#Gift | #7Days - #Day3 | #PDO | Ice Scraper with Replaceable Blades | NoahMillerDesign

This model was designed in Autodesk Fusion 360 for the Product Design Online #Gift 3D modeling challenge. In addition to the main design challenge, Kevin Kennedy of Product Design Online issued a challenge to anyone wanting to develop their 3D modeling abilities even more; create a unique 3D model each day for the last seven days of the main challenge’s timeframe. This is the model that I designed for Day 3 of this mini challenge.

Winter has officially arrived in Indiana, bringing with it the first snowfall of the season. While playing out in the snow can be quite fun, trying to go out anywhere isn’t when your car’s windows are covered in snow and ice. This 3D printable ice scraper is a perfect tool to keep in your car to ensure that you’ll always be able to clear your windows when you need to go out in wintery weather.

This ice scraper is designed in two separate components; the grip, and the blade. The more that you use any ice scraper, the duller the blade will get. With a normal scraper that you buy from the store, you have to throw the whole thing out and buy a new one when it gets too dull. To avoid being quite as wasteful, this ice scraper is designed with a compliant latching mechanism that allows the blade to be easily removed and replaced when it becomes ineffective. This also allows the grip to be printed using a different material than the blade, such as flexible TPU, giving the grip a more comfortable feel in your hand.

This model has been designed with FDM printing in mind. Both components are structured so that they will print without any support material. They also incorporate the appropriate edge geometry to ensure that they will print cleanly and prevent “elephant’s foot” first-layer expansion.
