Filament Package Pull Handle&Handle

Recently, I was troubled by the stacked filament package boxes. I have so many filaments that I have to stack them together.But it's hard to take out the filament boxes below. So I designed this— “Filament Package Pull Handle&Handle”. It can help to take out the stacked boxes easily.* Some types of filament may not be suitable for this model due to insufficient strength. * Do not pull it out too fast, it may cause the break of the swatch. I have tried and tested multiple different designs, it's really hard to achieve a balance of strength, feasibility, and usability.
