Creating Meaningful (& QUICK) 3D Printed Keychains

START HERE! https://bit.ly/3Dkeychain-go

So you want to learn to make a 3D printed keychain? You've come to the right place, but there's one challenge - you have to make it for someone else.

Use this tutorial in the SCCOE Wavemakers Makerspace to learn how to create a simple keychain for 3D printing. By the end of the project, you'll know the basics of three dimensional (3D) computer aided design (CAD) software like TinkerCAD, especially on how to resize and combine existing shapes.

Tools You'll Need:

1. At least a tablet like iPad or Chromebook, but faster on a full laptop
2. (recommended) External USB Mouse
3. 3D CAD design software - we'll use TinkerCAD, but checkout more sophisticated (but also free for educators and students) Onshape, Blender, or Autodesk Fusion
4. Access to a 3D printer, like the Bambu X1 Carbon printer now available in the Makerspace.
5. Slicing software, including the free BambuStudio

Materials you'll need:

1. PLA filament loaded into your 3D printer
2. (optional) keyring or clip

First you need to join the free 3D CAD (computer aided design) software to design your project.

1. Go to TinkerCAD.com and sign up for a new account. HINT: It's easiest if on a school Chromebook to use your school Google Account but you must know your password!
2. Login with Students Join a Class green button.
3. Enter your teacher's class code (see below) then green Go to My Class button!
4. Now you're ready to create! For this first project, you will be creating a new 3D design from your homepage.

Did you know?

Three dimensional computer aided design (3D CAD) software is used by industry level professionals and at-home makers to design both two and three dimensional designs.

TinkerCAD is a simplified version of Autodesk's more sophisticated software, used for new makers to keep your first attempts as friendly and fun as possible.

Tinker means to try to build or repair something, usually from spare parts, even though you might not be an expert...and you keep trying until it works. In our case, we're tinkering around with 3D CAD shapes until they group into a form we can send to a 3D printer.

In a new browser tab, open this Canva slide presentation by Jesus Huerta, from the Krause Center for Innovation Maker SPACE program.

Follow the prompts to do the planning of your design around who it is for and what they might need or want. It should be someone you respect, isn't famous, and that you can give your design to them at the end!

ELA Extension: Use this Gdoc template to write a 3 paragraph essay about your user.

In the Canva presentation, there's a how-to tutorial video on slide 9.

Open that video in a new tab, then follow along step by step to construct your 3D design in TinkerCAD.

Suggested dimensions:

x = width = 70mm ~ 2.75 inches/"

y = height = 7 or 6 mm ~ 2.5"

z = depth = 30mm ~ 1.18"

EXTEND: If you want to go further, think about the user and figure out how to convey who they are, what you respect about them, or a problem they need to solve in your actual 3D design. Think about adding symbols, shapes, icons to customize even further!.

HINTS:

Did you know you can change the LANGUAGE of the TinkerCAD interface (video)? ¿Sabías que puedes cambiar el IDIOMA de la interfaz de TinkerCAD (video)?

Keep the dimensions the size you want the eventual print: width no longer than 70 mm or 2.75" and height no thicker than .25" ~ 6 or 7 mm - bigger will be too large of a print to fit on a normal keyring.

Make sure to Union Group all your shapes (text, cuboid, tube) before you export.

Make sure to make your tube ring isn't too "skinny" to be strong enough to hold a metal keyring later. Make it even with the rectangle height or taller!

Send a message to your CAC teacher or Darren <dgertler@santacruzcoe.org> or Danielle and they will slice and print your project for you this first time!

EXTRA: Come into the makerspace sometime and we'll show you how to slice and print for yourself!
