DRAFT - will be released by 9/27 for 2017
Design a container no bigger than 5" x 5" x 5" that will house your RedBear Duo on or next to a mini breadboard (that is 3.29" x 2.15" x 0.33"). (The size constraint ensures that you can print your enclosure on the Afinia 3D printers in the Invention Lab and the Type A printers in Jacobs)
You're free to make the container look however you want. What's important is that it securely holds and protects your equipment.
If you are a complete Fusion novice or already an expert, you should pair up into novice/expert teams and solve this assignment together in groups of two. If you've had a little exposure to Solidworks beyond our tutorials but are rusty or aren't completely comfortable, you may also attempt this assigment on your own.
- The container should be made up of a top and a bottom piece. The two pieces must be shells and mate together cleanly with no edges protruding out at the seam.
- The container should have a cut-out that allows you to plug a USB cable into the board. Make sure you measure a USB cable - depending on how far you have to insert the plug into the box, your cut-out may have to be bigger than the metal USB connector itself to account for the entire plug.
- You will have to create a basic model for the Duo board. In particular, you'll have to measure the distance between the board edges and the location of the USB ports.
- At a minimum, we suggest you use two 4-40 Pan Head Phillips Machine Screws to hold the halves together to form a solid container. You will need to extrude features inside of the halves for the screws to pass through and hold everything together.
- Use www.mcmaster.com to locate 4-40 Pan Head Phillips Machine Screws. Once you find the screw, select the part number and download the CAD file) from the site to use in your assignment. (Optionally: Use 4-40 threaded inserts to avoid screwing directly into plastic).
- Assume the breadboard will be glued in place with adhesive.
- Create a single assembly of your container with both top and bottom halves, the mbed board, and the screws.
- The parts should fit securely inside and not be free-floating such that if someone dropped the container, its contents would not move around. You may need to create some geometry in your parts to mount or hold the internal components, or use fasteners (e.g., 4-40 machine screws).
- Create a dimensioned drawing for the top and bottom piece of the container with overall dimensions. Do not worry about dimensioning small features inside. Include the front, right and top views in your drawings.
- Create a front, right and top view drawing of your final assembly.
- Include a hinge or snap fits, to allow opening and closing the box without a screwdriver. Feature can either be printed or off-the-shelf parts from a hardware store.
- Add fillets to sharp exterior edges and modify ergonomics to make the container handheld
- Add a button to be able to push the reset button on the Boarduino
- Add an internal battery holder and battery (e.g., 9V).
Feel free to download and utilize relevant parts from http://www.3dcontentcentral.com/ to add to your assembly.
- Tell us who is in your group if you are submitting as a group.
- Submit your Fusion part, assembly and drawing files as a single zip file.
- Describe the strategy you employed to model the different parts and to fit them together. (1-2 paragraphs)
- Include images (exported or screencaptured) of your parts, the final assembly, and the drawing so we don't have to start up Solidworks to see your design.
- We realize 3D printing is slow and not everyone will be able to print their enclosure is by the deadline. If you can print it, include a photo and tell us if what you learned from the printing.
