This is a Garmin Vivoactive 3 charging stand angled at 35 degrees with a hole to plug the charging cable in the back of the watch. The hole is located at the top. Some other charging stands have the holes in different locations so be careful which one you choose.
Designed on CATIA V5, native file included.
Edit: As requested, I've included the STL file for the Vivoactive 3 Music which has the hole for the charger on the left side at the 9-o'clock position.
