A remix of the excellent Secure Locking Stand by Thomatron to have two stands per base. I've included two profiles, one for the figures facing towards each other (good for back-to-back poses too!) and one for the figures both facing forwards. You could also edit the model using MakerWorld's built-in customizer to adjust the exact angles of the posts yourself!

The stand is adjustable in 36° increments and is locked in with the printed thumbscrews.
