To prevent the screws that hold the motors from vibrating
loose and falling out just fill the plastic holder with liquid
silicone. (

Another way of preventing the screws from becomeing
loose and falling out is by using “screw” glue such as
Locktite Mild or plugging with light weight foam.
Using Loctite or silicone are not the best options as it will
cause disassembly problems later.
