MP Select mini (Malyan M200) MK8 Extruder Flex adapter

This is an adapter that, when installed in an MK8 extruder, restricts space for flex filament to bend after the extruding gear. It can be used with regular, rigid filament so I have it installed all the time. It also doubles as a M3x25mm screw spacer in the MP Select Mini (Malyan M200) printer, as these screws are a bit too long to fit into the extruder.
