Just a remix of this wonderful design to fit the K1 Max.
Because the Guide is now wider, you might need to print it with supports. For me it failed printing without, but that depends on your printer.
I also included my OrcaSlicer Project for this print.
The author remixed this model.
I extended the length of the guide and the roller to match the width of the K1 Max. It's about 86mm extra for a total of 222mm for the guide.
The roller without the pin is now 190mm, but could need a little bit more. The length works fine, it just has a little bit more space in between the guide than before.
