Vòng Đựng Mẫu Thử Filament

Works with most filament samples with holes. 
Very little filament, no box and no picking up samples from the floor!

Print settings: 

• 0.2mm layerheight
• 15% infill
• no supports

Break the opening apart after printing, slide your samples on the ring and then the tube and slide it over the opening in the ring to close it. You can open and close the ring later again to add more samples!
