Gear Making for a Toy Car
A youngster stopped by our library asking if the 3D printer could make a
gear for his remote controlled car.
I've never made any gear let alone one for a toy.
I was watching this YouTube of creating a gear in Tinkercad but wondered if
that would be precise enough for a gear replacement for a toy car?

The guy who instructs on this video keeps mentioning how it's not the most
precise to create in Tinkercad but must I first master OpenScad or
meshmixer to make a gear for a toy car?
Thank you so much.
Charles.
Use a gear library such as the one in BOSL2:

Have the youngster figure it out.

Whether you can print them or not depends how fine the pitch is and the
type of 3D printer.

The gear will likely be too small for good results, because the smallest
"pointy thing" you can make with a 3D printer is about twice the thread
width. For ordinary printers, that will be on the order of 1 mm, which
is rather chunky for a gear.
I did print change gears for my small lathe that may give you an idea of
what the end result will look like:

They're not particularly durable, but I don't do a lot of threading …

Related: I am trying to make some parts to attach to a golf trolley I bought. A key part appears to be a 1/2 - 13 threaded bolt. However, a 1/2 - 13 begins to stick when threaded in more than about .25 inches. I suspect they have used a different thread pitch to keep people from DIYing. I know about BOSL2’s threading library. I can experiment and find the alternate pitch.
But what is the best orientation to print a bolt around that size? Vertically? Lay it on its side with supports?

In the not so recent past, I downloaded a simple C-clamp from one of the repositories. The default orientation was vertical but that makes for a fairly weak screw/clamp. Horizontal orientation would create complications with supports and/or bed adhesion.
My solution was to cut away slightly less than one-third off the diameter and print it on the flat. Enough threads engaged to provide the strength and it prints beautifully.

The best way to print it to maximize strength, if you can make it work, is
to lay it on its side and just cut off a section so you don't need any
supports.
