Gear cell phone holder

I designed this table phone holder, using gear reduction and physics. Printing is very simple, no supports needed, assembly is not difficult, just a little bit of manual skill and some glue. Instructions: 1) Glue the phone base (RED) to the red gear and the red triangle with the hole. 2) Take the longest rod and insert it first into the base (WHITE) and then insert it into the phone gear (RED), 3) Continue to insert 2 more gears and finally insert the small gear. 4) insert the knob and the seger, at the beginning and end of the rod, just insert it into the flat part and then rotate it. 5) take the smallest rod and start inserting the thinnest gear; 6) continue to insert the other 3 gears, and finally insert the small one. 7) put the segers at the beginning and end. With this gear configuration, the rotation of the phone is slow, to speed it up, you just need to put, in the long rod, the small gear in the third position, and in the short rod leave the first three gears in the same posit
