That depends on which parts you crafted. If you made two diamond gears and a glass block, you only need a crafting table. If you made two diamond pipes, a diamond chipset, and a pulsating chipset you need an assembly table (and you will need it for the chipsets as well). Unless you already have an assembly table set up, I would recommend the crafting table.
