Extra center spacing for printer tolerance issues

[Tmasters]

When I 3D print Gearotic gears, they are too tight for the 'optimal' center spacing I specified in your calculator, due to 3D printing tolerance variation.  So I simply specify a slightly smaller (about 3 percent) center spacing.  But this means that the layout on your screen does not precisely match the layout in my real design, which is sometimes a small annoyance.  Is there a way to specify in your circular gear tool that the fit is to be more 'relaxed' than the theoretical optimal to allow for printing errors, so that the spacing on your display will agree with the spacing in my project?  Thanks!

Hi:

  For me, I keep the same spacing, but I print each gear at 97% size.. this usually makes them correct to
geometry, but you can also make the tooth width smaller, this relaxes the fit. Trouble is, the outside
diameter in 3d printing if often too large as well, in which case tooth width wont help.

  On trick is to make the tooth width .45, and print at 99%, this makes the diam of the gear small
enough to fit, and the tooth ( laterally) a relaxed fit in the mesh..

That's a great answer.  Thanks!  I'm ashamed I didn't think of just setting the print slicer to shrink the gear.  Elegant simplicity!
