Marble Run - Megabase (Joyin Compatible)

I got a request to create a large base for the marble run pieces I've posted. This was my first idea before I got all the input. I have two more in the works and a few other parts as well, but I'm going to need a few days to print everything.

This base has four inch on center posts on a hex all around the center. You could even join multiple bases together with a couple 4" slide parts.

The base is 250mm round.
