Here are SolidWorks blocks (If you are unfamiliar with blocks, check out some documentation here and here) versions of the 2015 FRC control system components. These include mounting holes and external dimensions of the parts and can be inserted into any sketch, which speeds up designing electronics layouts. Feel free to use these in your CAD this season.
