Yes - we can supply 3D .stp and 2D .dxf files for use in your CAD drawing program. These are available by contacting us with the part number of the reel you require.
Note that due to the individual nature of custom made reels, these drawings may not be available immediately and may need to be created for you. Also, during the process of fabricating the reel, measurements may change by fractional amounts. Please keep this in mind and allow a little breathing room if you're designing around one of our reels.
