Where can I get black plastic cube in specific dimensions for reasonable prices?
This is difficult because there are many plastic materials that are available in the color black. Small quantities of plastic cubes are normally made by cutting sheets into strips and then cross cut to make the cube. Black ABS, Black UHMW, Black Acetal and Black Nylon are all common materials available in sheet that can be cut to cubes. Also, the size of cube you are looking for makes this tough to answer. Solid plastic sheets are made from .125 (1/8) to over 2 thick. If you are looking for something larger than the 2 cube, it may need to be made by bonding sheets together to make a hollow cube - or box. Glad to provide more detail if you can supply some additional specifics on what it will be used for and the size range. Thanks
