Remixed Measuring tire groove without supports

Modified version of the original Measuring tire groove from Lopata_225 . I had a problem with printing the inner part that needs supports. Therefore, I modified the model so this part does not need supports and could be printed with the "numbers" side down. You can find two modification in files - The first uses the original scale 1 mm increments and the second works with a simplified scale and 2.5 mm increments. Recommended layer height: Base: 0.2 mm Inner: 0.1 mm Enjoy!
