###2020/3030 Filament Dust Filter What is it? --------------------- I kept losing my filament dust filter, so I created this to screw onto a 2020 or 3030 extrusion. There's space inside for an M4 nut. Slightly reduce the diameter of your PTFE tube with a knife and screw the tube into the nut. Make sure your filament still flows through without issues and place it inside the holder, then screw on the cap. Two versions are available: one with a 0.15mm tolerance between the hinge and another with a 0.25mm clearance. What do you need? --------------------- ### V1 * 2 10mm M3 screws and nyloc nuts. * 1 8mm M5 screw with T slot nut. * 1 M4 nut ### V2 * M6 pneumatic coupler * 8mm M5 screw with T slot nut. Changelogs: * 27-Dec-2018: Added versions that accept M6 pneumatic fittings, all V2 versions are like this. Also made the clamp a bit tighter so it stays better. They're all 0.25mm tolerance versions because that works fine for the hinge. * 5-Dec-2018: The tube was offset compared to my Titan extruder and this bugged me. Added an aligned version which has the filament path 13.5mm offset from the 2020 as indicated in E3D's Titan step file.
