Here is my phone camera stand.
The stand is made so it enables rotation in two direction. Only non printable parts are 16mm M3 screw with nut and rubber band.
I used PLA.
The Part 1 (the base) was printed at 70mm/s 15% infill 0.2 resolution and 3 perimeters (0.4). I used support but i'm sure it can be done with out it as well. It came out very rigid.
About other parts.
Other parts were printed at 30% infill. Smaller parts were printed at slower speeds to get better results.
Part 3 has two versions one si for bigger phones one is for smaller. For most newer phones print the bigger version.
You need part 4 two times.
I included .ipt fills (inventor files) if somebody wants to fiddle with it.
Support probably not needed but it can result in better print when printing part 1 (base)
