disposable putty knife

thingiverse

It's an incredibly versatile putty knife that can be scaled in x, y, or z dimensions to make it wider, longer, or thicker as needed. The default sizing was intentionally designed to create a usable and disposable knife for applying caulk and other substances that are difficult to clean up. With a weight of just 5g, the blade slices through with ease, while the generously sized handle provides a comfortable thumb grip. I recently made a second version with a curved radius on one side, which has proven to be an absolute game-changer for cleaning the inside of my grill. The previous design had caught fire once, but thankfully this new model makes quick work of even the toughest messes. And at just $0.05 per unit, it's essentially a disposable scraper that pays for itself time and again.
