BBC micro:bit CAD Resources - Kitronik University
This Kitronik University resource is part of the BBC micro:bit partnership and features FREE downloadable bbc micro:bit cad resources. These downloadable files are available in three different formats and have been made using Autodesk's Inventor Professional.
The bbc micro:bit CAD resources:
The team here at Kitronik have created a CAD model of the BBC micro:bit. We will be using this model to produce many of the resources we will be creating for the BBC microbit. We're sure these models will be useful for lots of applications so we are making them available completely free of charge, as we feel this maintains the spirit of what the BBC are trying to achieve with the BBC microbit project. Students and teachers (and home users) alike are sure to find them a fantastic starting point for projects based around the BBB micro:bit. The files are available in the following formats (see bottom of page for download links):
- .iam (Autodesk Inventor)
- .stl (which can be used in most CAD programs and for 3D printers)
This render was created using Autodesk Inventor Professional and shows the kind of images the files could be used to create.
Autodesk - FREE Educational Design Software
To use these files you will need some CAD software. Autodesk provide their professional software free of charge to Education and Home user which makes it an ideal choice. Autodesk gave the following reason for providing such easy access to it's products: 'Closing the skills gap starts in education. Autodesk are tackling this by providing schools with common access to the same advanced technology being used by industry professionals today. Autodesk provides schools, students and teachers with free access to its professional 3D design software. This will enable educators to introduce design thinking into our classrooms allowing students to imagine, design and create a better world. Using these tools to learn how to solve real-world challenges in new creative ways will be the perfect preparation for our the next-generation workforce. Equipping them with 21st century skills to meet industry demands and advance economies worldwide.' You can get a number of Autodesk software products for free, for both educational institutions and home use, check here for more information.
The above images are renders of the CAD files using Autodesk 3DS Max and Autodesk 360
How Kitronik Are Using The BBC microbit Design
We're using this design to create a few resources which we thought you'd find useful. One example is this cool poster highlighting the features of the BBC microbit (A4 download available below):
Another is this useful mechanical datasheet (download available below):
Using The Files When Creating 3D Printed Case Designs
Having the BBC micro:bit as a CAD object is incredibly useful when creating 3D printable (or laser cut-able) case designs. It means you can create your design with the knowledge that when you come to manufacturer the final design the BBC microbit should fit perfectly! An example use of this would be when designing a case, like this one designed by Chris Elsworthy from CEL Robox to create this great 3D printed case design.
Having the renders available makes this job much easier, and ensures an accurate result. We will also be using the files in our own models and case designs.
- .stp file (Zipped).
- .stl file (Outside shell only - For 3D Printing - Zipped).
- .sat file (3D ACIS Modeler - Zipped).
- Mechanical datasheet.
