Maybe it's just me but I'm constantly extruding filament that I then throw at the trash can and it inevitably hooks on something on the way there and ends up creating a layer of plastic hair on the floor. Well no more! It's not perfect yet but this little trash can does a surprisingly good job of catching and trapping filament that you drop into it's mouth. It also doubles as a holder for your tweezers. I've sized it to fit on my Fabricator Mini (so 70mm diameter - 2.75 inches). Prints in two separate parts. I didn't use a raft on the lid so as not to break the long thin sections. I printed in PLA, but the lid might be better in abs so the little arms have more flexibility. Though for me the PLA has not broken (yet), I tried to make it thick enough to survive but thin enough to have some flex. I also suspect that the PLA does a better job of not grabbing the filament as you drop it in, where ABS or something flexible would have more grip and prevent the filament from going through the lid.
