Fits directly into standard pegboard wall setups. The 4x4 Large size has 4 Rows of 4 slots for screwdriver storage. There's 2 models one with screw driver types embossed on the front and the other blank. Other sizes available in other models. Use tree supports to print it. Supports should only be needed on the back side for the pegboard pins. Otherwise is should print without any other supports when printed standing up as it would be in use.
