This is mount to add a dovetail rail on the right side of the Vaonis Hestia, to allow it to be mounted on standard telescope trackers. I use it to mount the Hestia on my Celestron LCM tracker.

To ensure a very stiff structure, I printed using 30% fill and 5 walls and top/bottom layers. Print on end to minimize supports.

Note: If your tracker alt direction can be set so that you can use a rail on the left side of the Hestia, it is easier to mount a rail on that side using the built-in 1/4" screw holes.
