Picture – The 3D Printed Raspberry Pi Camera.

Way back at the beginning of 2014 I published an Instructable camera called the SnapPiCam. The camera was designed in response to the newly released Adafruit PiTFT.

It's been well over a year now and with my recent foray into 3D printing I thought now was a good time to revisit the SnapPiCam and reinvent it as a 3D printable camera using newer and better parts 😉

I have called the new camera the Picture.

I have entered the Picture into the Raspberry Pi Contest, please vote for me 🙂

Step 1: Camera Components.

You'll need to gather up the following parts and equipment before beginning your Picture Camera…



  • 4 x M3 16mm Screws (silver)
  • 8 x M3 16mm Screws (black)
  • 4 x M4 Half Nuts
  • 4 x M3 20mm Female-Female Brass Spacers


  • 2 x Female DuPont Pins
  • Cable
  • Heat-ShrinkPicture - The 3D Printed Raspberry Pi Camera.

3D Printed Parts.

  • Attached are STLs of the seven printable parts orientated for printing and with a 0.5mm chamfer on the lower edges to help reduce elephants foot (picture_STL.zip).
  • The original 123D Design file is attached (picture.123dx).
  • Along with STEP files for the entire model (picture_STEP.stp).

Tools & Equipment.

Once you're sure you have everything you need, we can begin…..

Step 2: Equipment Test.

I learnt a long time ago now that it is best to check the electronics before starting on any design work.

It can be very disheartening if you go through all the motions of design and assembly to find that when it comes time to turn things on nothing works!

Firstly solder in the GPIO header and tactile switches to the LCD's PCB. I have removed the LCD panel itself to make things a little easier.

Next you'll need to run through Adafruit's DIY WiFi Raspberry Pi Touchscreen Camera Tutorial to setup the software. I had the advantage of having a Multibox PC with a Raspberry Pi 2 fitted enabling me to install and configure all the software on it rather than fighting with the Model A+ limitations. I setup the optional Power Switch and the DropBox functions for the camera. I recommend the auto load function too.

While the software is doing it's thing we can solder some wires.

The PowerBoost 1000 has an enable pin on the PCB cunningly labelled EN. Connecting a wire to EN and the other end to a switch and then back to GND on the PowerBoost means that we can control the power output and turn the camera on and off.

Next we need to take power from the PowerBoost to the Raspberry Pi. We're going to put the power into the Pi via the GPIO and not with the usual MicroUSB power socket. We don't want a cable sticking out the side of the camera all the time.

We need to choose the correct pins into which we can supply power, there is a helpful GPIO Cheat Sheet available from RasPi.Tv and checking the sheet we can connect +5v to Pin-4 and GND to Pin-6.

Now we solder things together. EN & GND from the PowerBoost to the switch, +5v & GND from the PowerBoost to the Raspberry Pi GPIO.

Plug in the LiPo battery to the PowerBoost, plug in a MicroUSB charger to the PowerBoost and let the battery charge a little while you sort out the software.

Once the MicroSD card is ready you can plug it into the Model A+ and turn it on. If everything went well you should see things on the little LCD.

If you're happy everything is working as it should we can move on…..

Step 3: To Begin | 3D Modelling.

I'm going to be using 123D Design to model all the 3D printable parts. If you don't already have it grab it for free from their website at http://www.123dapp.com/design I'll try to explain my methods but if you need to run through the basics there are plenty of tutorials to get you started.

The first thing I always do is find a suitable datum, the point from which all other measurements are made and the starting point for this project. In this case as we are using the Raspberry Pi Model A+ I have chosen the four M2.5 mounting holes are my first point of reference; the datum.

I measured the distance between the mounting holes and made a rectangle in 123D Design from those measurements. On each corner of the rectangle I put a 1.25 radii cylinder. We now have the datum we need to work from.

Next measure the board dimensions of the Model A+ and create a rectangle to represent it. You can align the PCB shape to the mounting-hole reference rectangle using the snap tool. From there go around the RPI and measure all the major components adding them to the model as you go along. I plugged in and included the WiFi dongle as part of the Model A+ model.

Repeat this process for each of the electronic components until you have them all modeled in 123D Design.

I did a rough mock up of where I wanted all the components to be in the camera.

Step 4: Building the Case | The LCD.

Firstly to make things a little easier I've given each component a colour using the material tools. Play around with the layout positioning each component in the orientation you want them. I added in four pillars to represent where I wanted the case screws to go.

Mechanical Sculpting.

I use the square solid in 123D Design to sculpt a case for the LCD. Place a basic 20x20x20 solid onto a face of the LCD model. Using the Pull function move the edges to encompass the LCD PCB, the LCD, the LCD's buttons and the four proposed case screws.

Create a copy of the LCD and move it away from the assembly for the moment.

With the remaining LCD increase the length of the LCD and the buttons so they protrude through the solid. You can use the Pull tool to do this.

Now using the subtract tool, subtract the LCD from the solid you just created. This should leave an indent of the LCD in the solid and leave cut-out for the LCD & Buttons.

Move the copied LCD back into place.

You can move the new solid away from the assembly a little so you can get a better look. I added a 1mm x 1mm ridge around the inside of the LCD cut-out which will keep the LCD from falling out.

Optional Tripod Mount.

I have a spare 1/4-20 UNC Brass Insert knocking around from another project. It just so happens to be the correct thread for standard tripod mounts. Seeing a great opportunity I added in a section for the brass insert on the base of the camera.

Step 5: The Next Level.

Using the same method of adjusting a basic 20x20x20 solid we can build the next layer.

The PCBs are held into slots in the layers so there is no need for any screws apart from the four case screws.

There are only two pairs of cables too so the system is very simple and great to work with. You'll just have to spend some time making space for all the components and checking PCB thicknesses.Picture - The 3D Printed Raspberry Pi Camera. schematic

Step 6: Surgery.

Remember to make a channel for the camera's FFC.

I went with 1mm thick and 1mm on each side.

Step 7: More Layers.

Keep building up the case to enclose all the components. Remember to make space for the components on the layers above them as well as under them.

Step 8: The Front.

The front of the camera is open to some artistic interpretation of what a camera should look like. I wanted the lens cover to be removeable so I put four M3 half nuts into one of the layers and made space for some matching M3 screws to hold the lens cap.

The final touch was adding the Picture name to the front and rounding off the cameras corners.
