About this 3D model
I like to use the old filament boxes from eSun and Sunlu to collect the leftover prints and poop for recycling. They are compact and sit next to the 3D printer. To make it easier to empty the container, I designed a simple funnel in Fusion360. The shape is chosen to fit into the side window of both boxes. Printing PLA is good enough, if you want to use it with any liquids go for PETG. 0.2mm layer height is ok, for fast printing choose 0.25mm no support needed brim is optional, depends on the build plate you use
