120mm fan mount for Flsun i3

This is a fan cover for Flsun i3 printer card. Fan and card screws must be mounted before fixing over card.
Built-in fans of i3 are 40mm, quite noisy and small. Common 120mm PC fans are better choice for cooling this card.
I am unaware of the boards of other flsun products. If dimensions are similar, this can be used on these too.
