This tutorial shows how you can design your own 3D Webcam Cover. You can follow the steps in the YouTube video or in the text below.

Step 1: Download FreeCad
For our 3D printed Webcam Cover we need a design program. We are going to use FreeCad for our design. FreeCad is open source software to make 3D designs. It’s free, user-friendly and works fine on Windows, Macs, and Linux computers.
You can download FreeCad via this link -> http://www.freecadweb.org/wiki/?title=Download
Step 2: Create your 2D design
First we are going to create the 2D contours of our Webcam Cover. To do this you create a new project and set your workbench into ‘Part Design’.
Click on ‘Part Design’ and select ‘Create new sketch’. Then press ‘OK’ and your workfield will be shown.
Now we are going to draw the shape of a rectangle. To do this you open the drop-down menu from ‘Part Design’ and in the sub-menu ‘Sketcher Geometries’ you select ‘Create rectangle’.
Draw a rectangle of 4 blocks with the focus point in the middle, the exact size doesn’t really matter.
We’re going to set the size of the horizontal and vertical side to 20mm each. To do this you select the horizontal side. Check if the line is now green instead of white. Open the drop-down menu from ‘Part Design’ and in the sub-menu ‘Sketcher Constraints’ you select ‘Constrain Horizontal Distance’.
Now you can set the horizontal lenght of your Webcam Cover. 20mm works just fine. Do the same for the vertical lenght but now choose ‘Constrain Horizontal Distance’.
We now have our own 20mm by 20mm 2D design of the Webcam Cover.
Step 3: Make a 3D design out of your 2D design
Now it’s time to give our 2D design some thickness.
Close the editing of the sketch with the blue arrow on your workbench. Make sure that your sketch is selected from the model tab on the left side. It’s probably called ‘Sketch001’.
We’re going to set the thickness of the design. Meassure the thickness of your laptop and add 3mm to it (1.5mm for each side of the Webcam Cover). It’s important that your Webcam Cover is not too loose. Otherwise it will fall of easily when closing the lid.
Go into ‘Part Design’ and select the option ‘Pad’. Set your desired length in milimeters and press ‘OK’. You now have a 3D box.
It is nice to give the Webcam Cover some round edges. So select the big square side and make sure that it’s green. Then select the option ‘Make a fillet on an edge, face or body’ from the workbench.
Set the radius to 3mm to give it big round edges and press ‘OK’. Do the same with the other opposite big square side of the 3D object.
We now have a nice rounded box in the size of our Webcam Cover
Step 4: Create a slot in the 3D object
The 3D object looks nice. But it is still useless for blocking webcam hackers. To make it usefull we will need to cut way the middle of our 3D object. To do this we’re going to draw the exact shape that we want to cut away.
Select the flat surface on the short side of the 3D object and make sure that it’s green.
Open the drop-down menu from ‘Part Design’ and in the sub-menu ‘Sketcher Geometries’ you select ‘Create rectangle’.
Draw a rectangle over your 3D object. The exact thickness doesn’t matter, but make sure that the rectangle sticks out on the right side.
We are now going to set the precise hight of the rectangle. Select the vertical side and make sure that it’s green. Open the drop-down menu from ‘Part Design’ and in the sub-menu ‘Sketcher Constraints’ you select ‘Constrain Vertical Distance’.
Set the lenght to the thickness of your laptop minus 1 mm. That’s 8mm in this case. Most top parts of laptops are smaller and in this way the Webcam Cover will stay in place more easily. Position the rectangle in the middle of the 3D object.
We are now going to give the rectangle round edges.
Select the option ‘Create a fillet between two lines or at a coincident point’ from the workbench.
Select the points where you want to start the round edge on the horizontal side and the exact point on the vertical side. Do this for both edges and press ‘Close’ on the left side.
We now have the exact 2D shape that we want to cut away from the 3D object.
To cut away the 2D shape in the 3D object we’re going to use the ‘Pocket’ function. Go into ‘Part Design’ and select the option ‘Pocket’.
Select the type ‘Through all’ from the pull-down menu and press ‘OK’.
We now officially turned our 3D object into a 3D Webcam Cover design.
Step 5: Save material, time and money
The 3D Webcam Cover design works fine now. But with 3D print designs it’s always good to look for possibilities to save material. Therefore we’ll be making a small hole in one of the sides.
To do this you select the flat surface of one of the squares. Make sure it’s green and press ‘Create sketch’ from the ‘Part design’ menu.
Now we are going to draw the shape of a round rectangle. To do this you open the drop-down menu from ‘Part Design’ and in the sub-menu ‘Sketcher Geometries’ you select ‘Create slot’.
Draw the slot and adjust it with the 2 red dots. Make sure that it’s in the middle and that it isn’t bigger than the square. Press ‘Close’ when you’re done.
To cut away the slot shape in the 3D object we’re going to use the ‘Pocket’ function. Go into ‘Part Design’, select the option ‘Pocket’ and press ‘OK’.
Your 3D Webcam Cover design is now finished.
Step 6: Save your 3D Webcam Cover design
You need to save your 3D Webcam Cover design into 2 file formats; as a FreeCad file in ‘.FCStd’ format and as a 3D printable ‘.STL’ format.
Select the last part in your model view on the left side. The name is probably called ‘Pocket001’. Make sure your whole 3D object is green.
Then save your 3D object as an .’FCstd’ and ‘.STL’ file.
Step 7: Have fun!
In these 6 steps you create a very basic but functional Webcam Cover. There are many other designs possibile. Use your imagination and create your own Webcam Cover!
