Adjustable SMARS Track System

This track is part of the SMARS_LCV variant, but I'm uploading it as a separate thing because the adjustable track system can be used on any current SMARS version.

Original SMARS is designed by Kevin Thomas and so far it's my favorite robot here on Thingiverse which is why I've spent a lot of time finding ways to make it work for more people on more different printers! I want this robot to work for ANYONE on any printer so I've been exploring methods to make that happen.

Problem: Across various printers and filaments, reports of the original SMARS track being too tight abounded...sometimes it was too loose and it would skip the tread on the slave wheel enough to become jammed. A designer has no way of knowing or accommodating this reality that some printers will overextrude, some will print with bad filament, etc... some people's printers will create a track that is too tight and some a track that is too lose. It has to be just right or robot will not function.
