Smartphone Holder, Videostand

This was just a quick and dirty project, i had take some closer photos with my smartphone and I needed a stand. So this is just the holder you can fix on a tube with 20mm or less diameter. I used my Proxxon Machine Stand.

Parts you need:
4x M3x20mm Countersunk Screw
6x M3 Nut, 2 of them are insert in the 2 slots.
2x M3 Screw
1x M4x45 Screw and a M4 Nut, or I take 2x M4 Nut an cut a M4 threaded bar.
