Dark Cap for Thrunite C2

This is a little cap for the Thrunite C2 Powerbank.
It's designed to be printed in a flexible Material, preferably a dark one.

My problem with the powerbank was the flashing LED. I use this while out hunting and in the evening/night this LED is really really bright...
...so using this cap I can access all ports and press the button while the LED doesn't disturb me anymore.

The Fusion 360 file is included.
