Arm mounting system 

• Added source file of basic arm - parametric (you can see the process of drawing teeth) (f3d)
• Added source file for bolts and nut  (f3d, stl)

It is a universal set of holders and arms. You can use this system as a notebook holder, tablet holder, monitor holder, camera or any other device holder or you can have it as a shelf holder.

If you print a pair, you can made various tables.

You can attach more arms togehter. I made some connecting parts and other accessories. 

There are no limits to imagination.

 I made it with increased strength and durability. If you add few perimeters the holders/arms can hold pretty good weight. 

Small light version

Holders reduced x 0.6 and then adjusted (hole sizes, gaps, etc.)

The holes for key in the screw and two arms have the same size as the holders in Honeycomb storage wall (https://www.printables.com/cs/model/152592-honeycomb-storage-wall). That means that you can hang different accessories on the arms.
