Raspberry pi4 Fan cover !

this is a very easy tool that might be very handy !!
This FAN COVER will help you to limit dust falling inside your raspberry pi 4
and also to reduce FAN NOISE !(i already checked temperature of raspberry pi and it remains constant
also after many days of being on !! )

If you bought this raspberry bundle :

and got raspberry case ( probably it's same size of other cases .. ) jsut like in the picture

than this small cover can be placed on it and it's going to cover the fan, if you need to move it to check the fan or if you need to remove it you can do it simply by moving left/right or just by lifting !
If u want it to stick in that place just place one single layer of adhesive tape !
