Gridfinity Storage for Router Templates

Gridfinity storage for the router templates developed by @warlogh. These template storage don't stack and are slightly off the gridfinity height standard (however that's not likely to cause issues). At this point in time, the threads to store the screw are tight - I'll explore options to fix this in the CAD model at a later date. I'm also intending to include a gridfinity 1x5 storage solution for the base.
