About this 3D model
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:32610
