Hello cDavi, welcome to the forum.
Some of the watchfaces made by members here for the prime 2 have custom touch buttons around the watchface. They are specific to that type of watch but could be edited. A bit like this one…
It is close to the one in the video. You may be able to search based on it at least.
I hope you get a reply from the member that created the original post, but it was 2 years ago and people do move on.
Personally, I would like to keep the box my watch came in as a storage or display box. Cutting it up to mount the charging cable that comes with the watch is interesting but a 3D printed cradle may be better for airflow. Explore the search function on the forum for a printed one, it is a great way to get used to the site.
