Iris Mechanism #3DPNSpeakerCover

The current model is to enter the #3DPNSpeakerCover challenge.

Inspired by the iris mechanism of the camera, this model acts like a cover with open and close mechanism, where if one wants to listen to mused they may open the mechanism and when done, simply rotate again to close.

The model is designed with parts which require no support to print and no glue to stick, just print and place to assemble.
