Simple and easy to print model no supports needed and no modifications needed once finnished printing other than adding the 2 ptfe tubes.
installation is easy just need a longer bolt to screw it it with (same as original).
Hope this print helps some people
The author remixed this model.
The changes i made from the original model was to shorten the arm that the spool was on so that it was closer to the printerand took up less space.
