Description
This the 10th revision of this extruder, it is now located and hosted here on the wiki , previous versions were located on thingiverse
it is a very simple Nema17 direct-drive extruder which can be setup with very little effort and uses one of the many 5mm ID filament drive hobs the mounting holes are compatible with just about every Prusa I2 and I3 carriage and adapter , there are no springs and no tension to set as it relies on a fixed distance between the 623 bearing and the filament drive, this has proven itself very reliable over dozens of spools of low quality filament
