I made another one of this excellent extruder design, this time a custom variant provided from the author. Thank you a lot!
This extruder is mounted on a NEMA17 and a 4mm thick sheet of aluminium, and thus the motoraxis is 4mm short for reaching the bearing. After checking the dimensions of the extruder, it should be possible to trim the model a millimeter here and there to get the bearing more to the motoraxis.
