comment How to export a ParametricPlot3D as .stl for 3D printing
You could just put a /. Line -> Tube on the end of your plot.

I recommend looking into the Select and Cases functions.

comment How To Replace $\rightarrow$ by $==$ in Mathematica's Output when using Solve
You do just like you said in the title. Use a rule on the rules: Rule -> Equal.

comment NonlinearModelFit indeterminate or not a list of real numbers
You can put in conditions on the parameters to avoid non-real numbers, but you're going to have trouble no matter what you do. You have a Log[A3 x] in there and you are trying to fit to both positive and negative x values. So you are always going to get a complex result at some point.

comment Display trailing zeros in ticks
There are a number of ways to set how a number is displayed: NumberForm, PaddedForm, SetPrecision. You could Map one of these over your ticks: {#, NumberForm[#, {5, 4}]}&/@ ticks.

comment Division by zero is slow
Clever and fast, but I'm going to wonder what the heck it is doing when I come back to read the code a few months later. Comments are for the weak.

comment Division by zero is slow
I like this answer the best. It's a bit wordy, but clear what it is doing. It's fast and flexible (if you want to do more than a simple divide). It's not quite so fast if you want to do a Normal afterwards - about the same speed as the case with no zeroes.
