Iphone 6 charging dock/ passive amplifier

Docking station for Iphone 6 with case, also works without a case as well just a bit looser. Works as a passive speaker and boosts volume to some degree (notice more of a difference in a bigger room). I was having printer issues so my first print does not look the best but is still functional (issues resolved now) - As soon as I reprint again i will upload pictures of it!.
Printed on the below setting -> designed in a way that support and infill should not be needed but if you would like to use
