Gyroscopic Gimbal Mount Plates

I love the gimbal mount made by BrandonW6 so much that I am giving screwless cube gear and mount sets as gifts. I needed a way to print more than one set at a time, so I made some plates for the bases. I made a plate for the rings too, but you still could only print one set at a time.
I made some grooves in the top and bottom of the rings so they will print as circles with no fill-in. I made some (plates or towers?) with 2-6 ring sets with spacers in between.
