The exact name of Poop line is Pre-feeding , which is a byproduct of every print. Its function is to stabilize the filament flow at the hot end before printing, to ensure that every print reaches the expected quality. （For：P1S/P2S/X2D/H2/X1） 

In order to make the workspace more tidy and orderly, I specially designed this bin. It can be hung on the edge of the printer without taking up desktop space. When the Poop line is put in, only a small part will be exposed. The double-hole design is not easy to be blocked and can accommodate more quantities at the same time. This is a simple and practical model, Looks cool? Try printing it now!
