An articulated arm for cameras or light, to be screwed permanently or fastened with a clamp. 

This is a sturdy camera arm, the lamp in the picture weighs 500g and it works great. Each joint is articulated and you can set the light exactly where you need it. 

You can have just one arm or you can fit several, there are two lengths to choose from. 

Threads
All M6 threads need M6 8x8 mm heat set inserts. The M3 thread on the camera platform is meant to be threaded directly into the plastic, you can easily do that with a screw if you do not have a tap.    

1/4" Thumb screw
The only special part that you need a 1/4" thumb screw for the camera/light, I bought this one for $2 but pretty much any one works.

Printing tips
Print everything in PLA or PETG with 4 walls/top/bottom, 15% infill. Use supports and brims where needed. Print everything in the direction in the STL, especially the cogged joints needs to be printed vertically and not horizontally.
