Belted extruder

thingiverse

Simple belted extruder, which is originaly made for Geetech i3 and was inspired by [Itty Bitty Belted Extruder](https://www.thingiverse.com/thing:389105) and [Belted Extruder v.3 for 1.75](https://www.thingiverse.com/thing:1764551). <h4> Important notice !</h4> The hobbed bolt used in this extruder is shorter than the common M8 hobbed bolt. To keep the size of the extruder as small as possible I used a regular M8 hobbed bolt, filed its head and threaded it as seen in the picture. This method work, but the generic hobbed bolt has a smaller diameter than 8 mm which creates a small gap ( this can be solved with a layer of sellotape). You could use a standard hobbed bolt, but you would need a standoff. <h4> Bom</h4> * 4x M3x5mm - for stepper * 2x M3x30mm - for tensioner * 1x M3x20mm - for guidler * 2x springs * 3x M3 nuts * 8x M3 washers * 1x Push-fitting with 9mm diameter * 1x 16-GT2 pulley * 1x GT2 Timing belt 180mm/90 teeth (can wary slightly) * 3x 608 bearings * 1x Nema 17 stepper motor * 1x Shortned M8 hobbed bolt * 2x M8 locking nuts The top part, which enables mounting is available here [Geeetech z-axes top and bottom mount](https://www.thingiverse.com/thing:2461406)
