Echo Tardis Cover

I have included the complete Fusion360 model file of all my modifications. This should make it a bit easier for those that wish to change physical details and sizing. I personally find that dealing with STL files a PITA and creating closed watertight models as problematic and at times somewhat challenging... But here is my results for all to share.
I have also included my STL files that were successfully printed and that were created from Fusion360 project here.
Enjoy, and as always I leave the modifications and updates as an exercise for those interested enough to do them.... batteries NOT included..
