Bar with shelf for the Monoprice Select Mini to hold the hinged filter and a little PTFE to guide filament into the feeder smoothly without binding all while cleaning and oiling the filament.

Uses the stock screws with washers. Print one of these if you haven't already (http://www.thingiverse.com/thing:190118) Glue it to the shelf at whatever angle works for you. Plastruct works great if you have it, if not good superglue should bond it just fine.
