Refine Printed Surfaces with : After supports are removed, small marks, edges, or layer artifacts may remain on printed parts. files allow controlled material removal to smooth edges, refine surfaces, and improve the final finish. Fine Teeth for Controlled Material Removal: Made from T12A steel, the fine-tooth pattern supports gradual, controlled material removal. It is well suited for refining PLA, PETG, ABS, and other common 3D printing materials. Four File Shapes for Different Features: The set includes flat, round, half-round, and triangular files for working on flat surfaces, curved areas, narrow grooves, and internal corners. This makes it easier to handle different printed geometries with the right tool. Reach Areas Sandpaper Can't: Narrow slots, internal corners, and small holes are often difficult to finish with sandpaper. The slim file profile makes it easier to reach tight spaces and refine intricate features with ., Manufacturer: Aundhegrtt
