This dock is designed specifically for the iPhone 5 and its new lightning connector. This dock is taller than others in order to accommodate the lightning connector's longer stress relief. This dock includes a chamber for weight such as BBs or lead sinkers and a cover which can be glued into place once the weight has been included.This design is parametric, but I designed it in Alibre CAD so it might not be as easy to modify if you don't have the software.10/17/12 update: I published a version of this dock for phones with a case: http://www.thingiverse.com/thing:32610Print the dock and the cover. I designed the cable channel to be narrower at the very bottom so you may need to clean it up with a hobby knife. Trim it so that you can just fit the cable through.I designed the lightning connector channel to be snug. I had to clean up my channel with a round file just a little before the connector would fit through. Once the connector is in position, run the cable through the cable channel .Fill the weight chamber with weight of your choice and apply the cover with glue.
