Didn't find anything for this so i had a crack at making my own, it's not perfect but it works well enough.
I used 6 perimeters with a 30% infill and it feels pretty solid, I've left the mount blank without holes so you can create your own depending on what screws you'd like to use.
I've also included the shell for the fit, so you can test the fit in vase mode without wasting filament, or create your own mount from there.
The author marked this model as their own original creation.
