Rugged filament sample box | Inset Remix | Sample thickness adjusted

This is a remix of @Kaksu3D's Rugged filament sample box remix to account for the 3.3mm thick samples (e.g. the customisable swatches from @Makkuro - https://www.printables.com/model/323399-filament-swatch). Due to the wider slits, there are slight gaps on the bottom outmost sample slits, which however do not cause any problems while printing (slight warping is normal) and still perfectly fit into the remix case by @Kaksu3D!
