Prusa Lack/Platsa filament feeder

thingiverse

This is a filament feeder that closely resembles the one from Prusa's Lack table design but I've enhanced it by 8mm, incorporated M9 threads, and included an M9 washer/nut assembly to secure it firmly in place. After discovering that the guide from Prusa's enclosure wasn't staying put very well, I scoured Thingiverse for alternative solutions. The one I liked best was @Rimbalin 's design but I found its inner diameter to be just a bit too small and resulted in excessive friction. (Occasionally tightly coiled PLA would snap as the extruder pulled on it) So I designed this filament feeder to closely match the Prusa's design while also securing itself firmly in place. The Fusion 360 source file is included for anyone who wants to make adjustments or tinker with it. UPDATE 2019-08-14: Parameters have been added to the Fusion 360 source file to simplify adjustments, and a 42mm version has been included as requested by @Merlin2k for Ikea Plasta.
