Articulated camera arm fastens down to a 2x4, and allows you to position your camera in "infinite" positions. Nominally cut with a laser cutter and 3D-printed. Could also be made manually, or with just a laser cutter or 3D printer by itself... Though using a printer would take a looonng time.Step 1: Video:
Check out the video for how I made this using a nominally 60W laser cutter.Step 2: Supplies and Tools
- 1/4" MDF
- 1/4 - 20 carriage bolts:-2" long for main links, 2 1/2" long for links that straddle 2x4, ~1" long for ball head
- 1/4 - 20 nuts, optionally 1/2" nuts
- Optional: Filament (if using 3D printer)
- Optional: Ball head (discussed later)
- Laser cutter (my intro to 60W unit)
- Optionally 1/4-20 tap
Cut out parts per designs found on GitHub (DXF and LightBurn formats available).
STL file for ball head also available there if you'd like to print.Step 4: Optional: Nut Knob
Using a vise, press the 1/4-20 nut into the 1/2 inch nut to create a sort of "knob." Clean the threads with 1/4-20 tap.
You could also use a wing nut, or possibly even just use a standard 1/4-20 nut, but this would make it more difficult to secure.Step 5: Assemble
Assemble the links using carriage bolts and nut knobs. Shown here is a section that turns the rotational axes at 90º, allowing you to move your camera in a vertical as well as horizontal direction.Step 6: Affix to 2x4 and Add Camera
Attach camera to 2x4, using the longer links to straddle it, locking the assembly down with nut knobs.
- Shelf setup is part of a 2x4 basics bench build [Amazon]. They supply the plastic framing, you supply lumber. Works really well IMO.
It's possible to simply screw a camera into the 1/4-20 threads on the end of the 3D-printed piece, but a better solution is to use a ball head. Different options:
- Small Rig ball head [~ $5 eBay]
- Joby ball head w/ quick-release [~$40 Amazon]
- 3D-printable Joby adapter (can be used with small rig device, but I didn't find it to work quite as well as actual Joby product)
Note that Amazon links are affiliate, meaning I get a small percentage of any purchases.
