Prusa MK3S drip tray/trash bin

thingiverse

When you change filament, the Prusa MK3S extruder is positioned in the rear left of the bed. More often than not, the filament ends up on the table in that area. This simple bin catches most of this debris for easier cleanup. It often collects any filament that oozes from the nozzle before/during the bed leveling routine as well.
