Rough draft, I haven't printed this yet to see if it fits. It's a replacement part for the pro-clip to allow a cable-jive lightning extension to fit. This is needed because the apple lightning to hdmi adapter is short and ugly The test2.stl was made from a different method, I'm leaving it here in case that one works better for you. I've also included the openscad files, as well as a version that take a standard lightning cable, which can be adjusted to size. This is the cable I designed this for: Jive Lightning Extension Cable. http://smile.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=B00GP08858Use openscad if you need to change the sizes for your cable to fit tight. Drill out the holes a little bit before trying to screw in the screws.
