I'm posting today a small project that I needed to record time lapse videos using my phone, it's a an adjustable phone holder.
you may find 04 parts to assemble using 02 M3 screws and nuts!
you can have a look to the pictures to see how to do that !
I'v also posted a video on youtube showing how I printed these parts.
