Parametric design for an astronomical Vixen dovetail. The length of the dovetail is customizable, as are the size and number of pockets (and therefore support ribs).

A sample 150mm STL is included.

Print with supports and at least 6 walls (8 is a good idea), ideally on one of the long side edges of the dovetail. Tree supports tend to be easier to remove. PETG or other stable material is recommended.
