This is a complete cover for the Mayflash Dolphin Bar, protecting it from dust (and also making it more pleasant to see IMHO) when not used. It features simple design with a stylish color line at the center (I made mine in red, you choose) and a little window at the back side for the USB cable.

No need of supports.
Print at 0.15 or 0.20.
You have to print the side file twice, then the center and the patch. Glue both sides to the center, then let dry and to improve sturdiness please glue the patch inside, at the back of the red line (as shown in photos).

Enjoy!
