About this 3D model

I prefer extruding filament with the Filastruder mounted vertically. This way it can be left permanently mounted on a wall taking up essentially zero floor space. This configuration however is more prone to pellet feed problems because the hopper feeds in from the side. To eliminate any pellet holdup or jams I fitted a vibrating motor to the hopper that shakes the feed hopper at regular intervals. It seems to work quite well and kept the hopper feed tube properly filled during a five hour 1.75 mm filament run at 30 inches a minute. I fitted the shaker to Ian Johnson’s excellent Vertical Filastruder Hopper found here on Thingiverse. Alternatively, I think it can easily be fitted to any vertical hopper of your choice.
