HT Filament extruder
thingiverse
Cheapest Filament Extruder Ever... Hopper and mounting brackets are printed using a 3D printer. Layer: 0.2 Infill: 50% The hopper print time is 20 hours, 47 minutes - 72.58 ounces / ~ 216 grams. Bracket print time: 3 hours, 6 minutes - 11.25 meters / ~ 34 grams. Tubes (central heating piping) and other parts came from a local hardware store or "AliExpress". See the parts list for details on price etc. Drill is one I had lying around with two speeds (set at lowest speed) and the button with the screw adjustment (this limits how far you can push the button). So, the drill's speed is set low, and the button is held in place by a cable tie. First test run done (see pictures). Some fine tuning and printing the hopper remains.
