Wall-Mounted Multiple Backdrop Paper Roll Pulldown Rack Laser cuttable

I didn't have a large enough 3D printer to print these, and I thought of a way it could easily be altered to be laser cuttable, I used 6mm thick ply. Two bracket parts should be sandwiched together and the backplate with the two holes should be cut twice, one for each bracket. the backplate with the big hole should be cut 4 times and stacked on each side
