Thanks to @GR_388774 and @@Thomas_50404 for their design. The watch charger (I use it for my AirPods) is not snug enough to hold the charger tight. I just put a piece of the purge line between the charger and the part. That will fix the “issue”.
The author remixed this model.
I just put a hole in an 73° angle in the mount to be able to remove the MagSafe charger in case.
