I remixed this model to be able to fit 25mm base miniatures inside of the medusa's tail, and added a staff. I've included the blender files with the skeleton that I used so that you can repose the model if you choose to. I recommend printing the parts separately and assembling them, but I did include a combined version for those of you who want to avoid seams. The base is hollowed out so that you can weigh it down with washers or nuts to counterbalance the medusa's pose.
The author remixed this model.
I took the staff from an abjurer in the monsters of the multiverse collection, and used the Hythonia model from the mythic odysseys of Theros collection. The base I've included is hollowed out so that additional weight can be included to counterbalance the miniature leaning off of the base. I reposed Hythonia to hold the staff and to restrain another miniature.
