Hello everyone!!  I've had many people ask me where to go to get the base models for this marble run.  This marble run is made to work with the gridfinity system so you should be able to use any gridfinity base out there unless of course it has been modified.  Still though, I thought it would be much easier if I just made an expansion set with a bunch of bases, so thats what I did…. However, I did'nt want this to be that simple, so I added a piece that would allow you to elevate a base over top of another base allowing you to make higher runs with less supports.   This ended up being much cooler than I thought it would be so I'm very excited to share it with you!!  I designed this peice so that it will keep the same height just as if you stacked supports to the same height making the elevated base seamless with surrounding structures.  I also drilled a hole through it so you can pass Pete's drop pieces right through the elevated base.  I think this set is going to lead to some awesome creativity in all of you!! hope you enjoy it!  Happy Printing!!!

ATTN!! This is an expansion set. You will need the core set and some of the many other sets available in order for these pieces to be useful. I have links below for the core set and a collection with all sets from Pete and Myself.
