HighCloud MicroscopeCamera Addons

I recently bought one of these fake "HighCloud" microscope cameras from aliexpress, which basically works great.
But several details are not acceptable. In two details, I could improve the construction.

First is the aluminium ring holding the camera. It does not fit in diameter and height, giving a very vulnerable strength. So I made a fitting one, melted in three M4 fusion threads for the grub screws et voila, the camera is tight from now on.
The other thing is the holder of the ring light. It is attached by three long shaky screws which destroy the thread they are pressing on. I made a ring which can be screwed (without a thread) on the ocular and takes the three screws tight.

By the way - I glued a magnet to the remote control so it can't get lost anyymore. Thanks to "MostOfFun" on YT for the idea.
