Tire tread depth gauge

thingiverse

This is my version of a tire tread depth gauge, designed to quickly measure the depth of tread on a car's tire. The scale ranges from 0 to 8 mm and only these two numbers are displayed on the scale. Above it, there's an "instructions" section that clearly states there's a 1 mm gap between each mark on the scale. I've created multiple versions of this gauge, but achieving a precise 1 mm scale has proven challenging with my printer. To overcome this issue, I colored the 1 mm marks white using a corrector to make them easily visible. Additionally, I marked the 4 mm line in red as it's the limit for winter tires. The design features a small bump on its outer edge to prevent the inner part from falling out. This gauge was created with a resolution of 0.1 mm, but you may be able to achieve an even higher level of precision by experimenting with different resolutions.
