Cellphone holder for gorpo mount

This is a cellphone holder, compatible with gopro mounts, perfect for taking videos, or video conferences, or live broadcasts.
I use it together with a gopro chest mount, to take video while walking or working, without holding the cellphone

Printed in PETG, but can be PLA too. For cellphones up to 10mm thickness

Update!

Version 2: I extented the base, as well as the bracket for better support and clearance (still 10mm thickness)

Vesrion 3:  For thicker phones, or phone with cover, up to 15mm
