It is the iphone SE or 8 case. One design has dual stands so you can prop it up on table and comfortably enjoy whatever it is you are watching. The other is a regular case. Both has audio ducts that direct sound from the bottom speakers to the front.

Printing in the vertical orientation with the audio ducts at the top, is the best printing position for both designs. Supports need to be added. For the dual stand iphone design once it is printed and you got rid off the supports. you should be able to move the stands or arms by applying a bit of force. Sanding is required to make the stands or arms fit to the case.
