Filament sampler (economical one)

thingiverse

I came across several filament samples, but they were consuming too much filament for my preference, so I designed a more economical alternative. There are two versions available - a round and a square one; personally, I favor the square one. The small hole is 2mm in width, allowing you to keep tags organized using filament. The square design measures 25x25 mm (just short of an inch), while the round one has a diameter of 25 mm. The frame height is set at 2mm, and the three layers are precisely 0.4, 0.8, and 1.2 mm thick. Printing only takes about ten minutes and requires approximately 0.3 meters of filament.
