This is easy to make Steadicam. This requires minimal hardware (you only need a metal quarter-inch rod) as all the parts are held together with friction. This is a great example of an engineering solution that teachers can use to teach in the classroom. From taking measurements with a Vernier caliper and sketching various designs to a final product, one can easily see how with 3D printing, your imagination is your only limitation!
A great companion for the Steadicam is this lens clip
*Requires quarter-inch rod (threaded or non-threaded) and counterweight. For my counterweight, I attached an empty 12 Oz water bottle filled with sand at one end of the rod.
I first scavenged for parts that I had laying around in my miscellaneous parts box. I was limited to four 608ZZ bearings (the ones you find in skateboard wheels) and one 12-inch non-threaded quarter inch rod. I took the measurements of these two parts and designed around these parameters. I used Solidworks to model the designs and then exported the design as an .STL file. The slicer engine I used was Cura, which is a free, open-source slicer engine. From the slicer engine, I exported the toolpath that my 3D printer can use as an .gcode file.
Objectives: The objective of this project is to teach students and people alike what the procedure is for engineering your daily problems. This project teaches you step by step by showing you the parameters and limitations that engineers have to work around, designing,
implementing, and sharing.
Audiences: The appropriate audience is anyone with a keen interest in learning, really.
Preparation: Obtain the required resources, which are four 608ZZ bearings, one twelve inch, quarter inch rod (threaded or un-threaded), a 3D printer, and filament of your choice.
Set out to solve a problem. In our case it is, "How do you stabilize a camera for smooth recording using easy to find resources, gravity, and friction?"
Find your resources! i.e. scavenge or buy four 608ZZ bearings (these are bearings found in skateboard wheels) and a twelve inch, quarter inch rod (threaded or un-threaded)
Take the dimensions of such resources!
Draw sketches on paper.
CAD the sketches based on your sketches using your CAD software of your choice (I used Solidworks).
Save CAD model as .STL, export it to your slicer engine of your choice (I used Cura as it is open-source) and slice the CAD model using your preferred settings. I used .2mm walls at 15% infill)
Save gcode and send it to your 3D printer (I used a 3D printer kit called the RepRap Prusa i3)
Results: At the end of the project, you should have learned the procedure of engineering real engineering problem (in our case it was, "how do you stabilize a camera for smooth recording using gravity?") In doing this project, you have learned to work with limitations i.e. lack of resources prompt engineers to find cost saving solutions to reduce cost of materials by using ingenious solutions such as holding parts together via friction instead of nuts, bolts, rivets, and the like.
