Unit 3: How Do I Find 3D Models to Print?

Target Objectives:
Upon completion of this unit, participants will:
- Create a simple 3D model in TinkerCAD featuring cuts and a hole (teacher led).
- Create a keychain of their own design (student led).
- Download a 3D model from Thingiverse to be 3D printed.
What is 3D Modeling and Where Can I Get Models?
3D modeling is a process that takes a 2D (something flat) idea, and creates them using 3 axis of movement (thus 3D). Objects will have a length, a height, and a depth creating an object the looks like something you would find in the real world. Many industries use 3D modeling techniques including (but not limited to) engineering, animation, architecture, and fashion designer. Modeling software is typically very expensive, especially if you're talking a large company, but there are options out there for people that just want to play and learn with it that are 100% free!
Special Note: Before jumping into any kind of modeling software and making it part of your curriculum, make sure the software is approved through your school. There are a ton of them out there, so if you find one you like, it's worth double checking.
We are going to explore a software called TinkerCAD and it is Google based. I find that it is very easy to learn the basics but takes a long time to learn how to do truly complex objects. Many classrooms utilize this technology because of the simplicity of this software to help expose students to the idea of 3D modeling.
If 3D modeling isn't something you're interested in introducing, you (or your students) can also check out a website called Thingiverse. It is an online database of already made 3D models that anyone can download and then upload to their 3D printer. This database is enormous, but luckily there are filters and a search function that help narrow down your selection.
Summary of these ideas:
- 3D modeling is a way to visualize 2 dimensional ideas
- There are lots of free softwares out there but make sure to check with your school first before curriculum implementation
- TinkerCAD is a free 3D modeling that is easy to learn basics
- Thingiverse is an online database of 3D models that can be downloaded
Activities:
Activity #1:
Create an account at TinkerCAD.com, then follow along with this TinkerCAD Video to create your first part.
Activity #2:
Now that you have a basic idea of how it works, it's time to create your own part. You're going to create a keychain with an overall size of 3 inches by 3 inches by 1/4 inch thick. Make sure there is a hole for your keys and make it creative!
Activity #3:
Create an account at Thingiverse.com, then follow along with this Thingiverse Video to search, filter, and download your first part.
Reflection Activity:
If you are in a group, feel free to share your 3D designs with each other and ask questions about how someone did something that you didn't know how to do. Also within your group, share any model you found on Thingiverse and discuss how you could use this within your classroom.
