Using this deburring tool is easy. First, hold the tool firmly. Then, gently run the steel tip along the edges of your 3D print to smooth them out. For corners with artifacts, carefully use the tip to remove them. When using, don't apply too much pressure as it might damage the print. Regarding maintenance, keep the tool dry and clean. After each use, wipe the steel tip with a soft cloth. If the blade gets dull, you can easily buy a replacement blade from us and swap it out for continued effective use.
