Filament Feeding System AM8 - 4mm PTFE

thingiverse

This is a remix of the Modular Filament Feeding system. I recently upgraded my Anet A8 to the aluminum AM8 frame (https://www.thingiverse.com/thing:2263216) and started converting it to an E3D V6 hotend and bowden setup. I wanted to dispense my filament from a DIY drybox and run it up to the printer through PTFE, terminating it near the bowden extruder motor mount (https://www.thingiverse.com/thing:2551526). This allows me to switch filaments without opening the drybox. All of the PTFE tubes terminate at this part, then go a short distance to the extruder to make changing filaments easy but minimize exposed filament to the air. I have included the Fusion 360 files for both mounting locations. There is a version to mount on the side of a 2020 or 2040 aluminum extrusion or to the right-rear corner of the printer, just under the corner bracket. The rear mount should also work for the left-front corner of the printer. VERSION 2: I have uploaded another STL for the right-front corner (which should work for the left-rear corner as well). Front mounting on the right side keeps the bracket up higher on the vertical extrusion and away from the X-Axis motor that is on the left side of the printer. UPDATE: I've been working to easily switch out filament for about three months now, and the PTFE tubes fit nice and snug so they don't fall out.
