Naked iPhone problem

One thing that immediately bothered me about the Insta360 Nano to iPhone interface was that I had to remove my iPhone case in order for the Insta360 camera to mount on the iPhone using the lightning connector.   I emailed Calvin of Insta360 tech support about this:

Where can I get an lightning extension.  The camera doesn't fit over my Apple leather case.

To which Calvin replied:

Sorry the camera need to use without the iPhone case.
Or maybe you need to order an lighting extension of your own.
It is available online or in the shop where you have the phone accessories.
Best Regards

To which I replied:

The update at the bottom of this page said it was coming in August:

"Meanwhile, Insta360 told me that they will have a lightning adapter in August to enable the Nano to connect to iPhones other than the iPhone 6 series.  I'm hoping the same adapter will enable me to use the Nano with my case." 

To which Calvin gave no reply.

So I googled around and found and ordered the DockStubz lightning adapter for $18.95 US at http://cablejive.com/dockstubz/ :

I hope the dockStubz allows me to connect the Insta360 Nano while keeping my iPhone case on!

Update [Dec 17]: The dockStubz is too square for the Insta360 Nano to fit!   $44 Canadian dollars wasted!  Then Nano is designed to fit snuggly over the iPhone's rounded edge and the dockStubz adapter is all hard square edges around which the Nano will not fit close enough for the lightning connection to take.

Update [Dec 27]: Filed the dockStubz using this nail file, laying the file down on a table and rubbing the dockStubz over it back and forth for a couple of minutes:



And it now fits over the iPhone leather case!
