I needed some way to mount my Nokia Lumia 920 to tripod (Hama Star Pro 59, with 43 mm insert). I was unable to find anything suitable, so I created and printed one.
This thing is built from scratch, but inspired by iPhone 4 Clip Mount for Velbon Tripod from kwalus. The main good idea is that the thing isn't printed in its entirety, but consists of two parts snapped together.
Print the two parts and insert the longer end of
Nokia_Lumia_920_top to square hole in
Nokia_Lumia_920_bottom. It might be a good idea to glue the parts together using hot glue or something similar.
The phone part is intentionally made very snug, for reliable grip. Slide the phone trough the side with shutter button and press the button to slide in.
