A set of curtain hooks and a mounting bracket to hang mesh material over the trailer door to keep mosquitos out.
From an experience: in such a small trailer the curtain sometimes gets sat on, which pulls it down. The design here thus uses a double-side tape to mount the curtain rod and not something permament. This way it isn't the curtain or the hooks that gets torn, but just the rod pops out and can be re-attached.
Not pictured: it also uses stick-on magnets and metal pieces clamped on the material to make the curtain stay in place.
Uses M2 screws to make sure the material doesn't slip out.
