This is an adapter for the Belkin PowerHouse Charging Dock. This model allows the use of a Lightning to Type-C adapter so that you can continue to use your dock. I used these Lightning to Type-C Adapters from Amazon (LINK). I printed this in TPU and used double sided clear mounting tape (LINK) to secure it to the dock. You'll want to use some hot glue to secure the adapter to the model so that when you pull your phone off it doesn't take the adapter with it.
The author marked this model as their own original creation.
