Phone Holder Arm

This model is a phone, tablet, or book holder that lets you read or watch stuff hands-free. The arms can move at 45 degree intervals and are fastened by m20 bolts and nuts.  

I have included step files for the start and end brackets, so you can edit to your needs. The included STLs are for an iPhone 11 that is mounted to an 80 mm headboard. 

For the setup in the image, I have used 4 male to female arms and 1 female to female for the last part before the 90 degree bracket. Used 8 bolts but only 3 nuts since all other parts except for the arms have internal threads. 

Material: PLA or ABS (PETG or PLA+ is not recommended as they are too flexible)

Supports: Not required

Resolution: 0.2

Infill: >35%
