So this is frame for 5m led strip with diffuser that 10mm wide.
I cut model in pieces to fit on 300mm bed, but you can try to divide it in even smaller pieces.
I would recommend to print in without bottom shell, so you waste less filament, after printing just glue prints together and insert led strip in it.
