Arrrggghhhh!

So, forget the "snug" setting. It does not adjust for this problem.

So, I changed:

reel_axle=13

to:

reel_axle=13; // [13:0.1:14]

So I set it to 13 to generate STL for the "friction wheel", and bump it up a tad when printing the "spool left". Since the value is used for both.

You could do something like:

reel_axle=13; // [13:0.01:13.5]

The point is instead of having a HMI widget scrolling whole mm, you can scroll part there of.

That line of code is sitting in the PushPullFeeder.scad file at this git site.
