Hack filament sponge cleaner

I needed a sponge filament cleaner, my printer nozzles kept jamming. So before i printed one i just used 1/4 of an old kitchen sponge and a 1" wide binder clip. This works! It slides along the filament until it hits the feed tube and then the filament slides through it. The clamping force can be adjusted by how deep the binder clip grabs the sponge. The .stl file is just a place holder (its the bottom clamp to a handle bar mounting bracket I'm working on).
