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 have also included my STL files that were successfully printed and that were created from Fusion360 project here.
Enjoy, and as always I leave
