    Make & Materials

    We recommend using ABS filament or another material amenable to vapor smoothing to print this toy with supports. In lieu of vapor smoothing, you can carefully sand and examine the fine textures to be sure there are no sharp points. Always wash thoroughly with soap and water before giving to a child for supervised play.
