Belted extruder by Drasko

Last crawled date: 3 years, 1 month ago

Simple belted extruder, which is originaly made for Geetech i3 and was inspired by Itty Bitty Belted Extruder and Belted Extruder v.3 for 1.75.
Important notice !
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.
