Print the dock, cover and connector support.

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 . Finally insert the connector support to help hold the connector in place. You may need to scale the connector support height depending upon the thickness of your phone's case.

Fill the weight chamber with weight of your choice and apply the cover with glue.
