The CINEZONE by Dora Goodman for the GOODMAN ZONE is supposed to be mounted with magnets and M3 bolts, which unfortunately don't provide that much stability as their contact surface is between two parts.
These brackets improve the stability of the whole setup by clamping the CINEZONE to the ZONE with proper contact surfaces.
You can use any kind of M3 bolts or thumbscrews or set screws with at least 8mm thread length, up to 16mm thread length for the bottom and up to 20mm for the top.
Please be aware that the CINEZONE Universal Shade was designed with some inconsistencies, so these brackets are not just simple mirrored parts.
The author marked this model as their own original creation.
