I like this guide better than others I've tried. It did require some finishing work.

  • The center hole in the spacers had to be drilled out, they were too small for an M4 to go through it without it cutting threads.
  • The flat side of both spacers had to be filed down a little to get them (with the bearing) to slide into the guide.
  • The wheel wouldn't fit on my bearing, I reprinted it at %102 (X &Y dimensions only) which worked perfectly. YMMV depending on the bearing.

This is a great mod. I had to file out the spacers though, as the screw wouldn't fit through. I'd recommend updating the spacer so the hole size matches what you've done on the main piece, as the screw went through that perfectly.

Thanks for the feedback :-)

I've discovered if I move the spool holder more into the middle it is even better and chances are lower that the filament jumps out of the roller.

Works perfectly well, nice job.
