Hi,

No glue below. Fit it in, then glue around. Once you know the hot glue, you can stick anything with barely just enough glue to hold firmly and at the same time to remove it very easily.

In case like yours, where fine elements can be damaged by pulling by hand or lifting with screwdriver/that's what i do/, so use alcohol.

I can't imagine a life without hot glue :-)

See some example, just right now what i have on my machine. The wood is bend, that's the weights are for. See how little glue i use. you do the same, just your element will be a little inside the fixture hole :
