(Yet Another) Filament dust filter

I liked the filament dust filter from Thing #190118 (by sneakypoo), but the latch on the lid is designed with the inside edge exactly matching the curve of the outside edge of the flip side of the filter; so when the lid is closed, the latch exerts no pressure and the filter wants to pop open. This version just bends the latch slightly to make sure the filter stays firmly closed while in use.
