This is a stand for the Roper modeled by mz4250 found here: https://www.thingiverse.com/thing:4907908.
My plan is to use it with a stalactite version of the Roper (here's mine), then swap out when the roper reveals itself. Not an original idea, but I wanted to put here what I came up with.

The stand height was just a guess, and can be easily adjusted.
