Filament guide roller design

prusaprinters

A filament guide with a roller design, for smooth filament feedThis is a remix of a thingiverse model (link at the bottom)I remixed it so it can be attached to the top of a piece of extruded aluminiumDesigned for the KP3S printer, but can be used for other printers as wellthe goal of this print is to feed the filament from the top into a direct drive extruder while having a spool on the table next to the printer.you'll need a M5x8 screw and a nut to attach it to the aluminium. You can also use an M5x16 with 3 nuts if you can't find M5x8 in your local store.Print the roller and axis standing up, the axis needs a brimBody needs supportlayer height : 0.2mminfill : 20%4 shellsoriginal thingiverse model : https://www.thingiverse.com/thing:3095575
