When using the multi material unit with the Prusa MK3S+ sometimes the filament is pushed back through the buffer to the spool. It gets entangled and the result is a failed print. The check valve increases the friction when the filament is pushed back. It can be attached to the end of the 4 mm PTFE tube with a M3 screw.
Printed with PETG and 15% infill
