2x4 brick

this is a 2x4x6 brick. my first thing created in fusion 360. i need to raise items in my basement after a recent flood and wanted something the size of wood but waterproof. it was easy to make but takes a while to print. please enjoy use however you want. (fyi the 2x4 portion is the same as wood 1 1/2"(38mm) 3 1/2"(89mm) and the 6 inches is actual 152mm)
