In this weeks layer by layer we’re going to take a look at making an enclosure for the Raspberry Pi A+.
In our previous project, we created an enclosure for the Raspberry Pi B+, so we’re going to make a copy of that and modify the model slightly to make an A+ version.
The A+ model features the same mounting holes from the B+, so we can leave those as they are. The A+ includes just one USB port, so we can delete the extra USB and ethernet port.
The A+ PCB is 65mm long, so it’s 20mm shorter then the B+ model. We can use the pull face feature to reduce the length of the PCB. Now we can move the USB port over 20mm to accommodate for the size change. The width of both A+ and B+ are 56mm, so that stays the same!
The HDMI, Micro USB, SD card slot and A/V jack are also in the same locations as in the B+ model, so we don’t have to move any of them.
In the B+ case, I didn’t make openings for the camera/display connectors or the GPIO header. So in this A+ version, I measured the cables and modeled each part so we can use them to create cutout openings. Using the combine/subtract operation, we can cut out these openings in the top cover so cables can pass through the top.
The case ended up being 20mm tall and 1.5mm thick so its small with a little wiggle room. There’s enough clearance for all the cables to pass through and it’s easy to reuse the A+ model for other projects.
I hope this simple enclosure helps you with your Raspberry Pi projects and feel free to download and customize the model. If you print one out, please share and post it up in the Adafruit forums.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
