7. Creating a 3D Model with Tinkercad
Chapter 6 , Free 3D Modeling Software , ” introduced you to Tinkercad, one of the
easiest CAD applications available. Add in the fact that it's free to use, and there's
really no excuse not to give it a try. If you find it's not for you, you'll want to
run through Appendix A , 3D Printer and Modeling Resources ,” because I'll also
be listing some other free CAD applications for you to try (as well as a few good
CAD apps that aren't free but won't break the bank).
In this chapter, I use Tinkercad to do some designing and create something that
I print on the Simple. I use most of the tools you read about in Chapter 6 , but I
also show you a few other features and tasks that you can (or should) do when us-
ing Tinkercad. I encourage you to log in to Tinkercad and follow along with the
chapter.
Hello World
I'm not sure whether you know anything about computer programming, but pro-
grammers use what are called programming languages to create the various ap-
plications (for mobile devices) that we all enjoy using. For decades there has been
a tradition in programming courses and topics that has a novice programmer cre-
ating a program to put two simple words up on the computer screen: Hello World.
I'm not one to break tradition, so the first item I want to create for my new Prin-
trbot Simple is a variation of the Hello World task. To celebrate the successful
assembly and testing of my Simple, I want to print out a small medallion that I
can tape or glue to the side of my 3D printer. This medallion will have the words
“Hello World.”
If you'd like to make one for your Simple, follow along as I show you how I
design this small object. Keep in mind that there's not a lot of surface area on the
Simple except for the printer bed, and I can't put the medallion there! I've de-
cided that the side of the base shown in Figure 7.1 is a great location, so I've taken
some measurements to determine that the medallion will have a maximum length
of 50mm, a width of 30mm, and a height of 4mm.
