The CNC Platform MDF Wasteboard from Snapmaker is a replacement board used to act as a platform for your cutting and sculpting CNC head. The MDF material is lightweight and relatively soft, allowing the CNC bits to easily cut through in case of a miscalculation. This particular item is designed for the A150 Snapmaker 2.0 3-in-1 3D printer, making this ideal for anyone who wishes for a replacement or would like to have an extra on hand to reduce project downtime.
