I'm a happy user and big fan of the BaBo Organizer System from Willi3D . This is a custom insert that fits his Drawer Modul 60 perfectly.
I prefer the larger stepped filament samples to be able to check the translucency at different thickness levels. A very common Filament sample are the ones used by the mobile carry box of Simply Models & Extrutim . I wanted to have a large assortment in my BaBo Drawer so this insert was born. The insert for bulk storage at home, the carry boxes when I want to take them with me.
My inserts match the original dimensions of the BaBo Organizer and occupie a 3x3 grid in the 60 Drawer. There are different plates with labels for different types of filaments.
