Version 3 :

1. lightened structure -- less print time
2. improved design -- more fillets make the model more beautiful. 
3. A clipping system is added to stop the remote control to fall out
4. Last model was too small for the remote control to fit in, dimensions are adjusted

Last model was a prototype . I made some modifications on the design and dimension. It reduce the printing time to 2 hours instead of 4 hours.

Here is my first 3d model to print -- a clip for remote control of gopro hero 3

With this clip , the remote control can be fixed on a mono pod to facilitate the control of gopro
