Summary

I made a few modifications to the orginal file, to be more printable, i removed the top clips ridge, because it make it bend in the wrong direction when you try to remove it from the case, if you have printed it in the vetical direction.
also I removed the lower end , so you can print it upside down without support
And finaly I made the side clips longer because it printed badly where the acoustic holes are and there was no clip ridge.
