GraviTrax compatible piers

These pillars (posts, or technically, bridge piers; I learned others call them spacers) have been designed and printed because my son got an amazing new toy from Ravensburger: GraviTrax marble run. And of course, during the holidays, we needed more piers to get the marble run built the way we wanted.. we needed.

So here they are: Extra piers to support the original GraviTrax hexagonal base plates.
Optimized for printing time, not for beautiful design. Needed them desperately!

Update:
My original version without tunnel turned out to be a bit more stable (high marble speeds). So I added them here too.
