Filament spool holder for Prusa i3
by misan, published
It allows you to have the spool mounted on the top of the i3 frame.
I have used some wood leftovers that happened to be 6mm thick, glued together. And though I am positive there are tens of bearing holders for filament spools, I designed my own, as I thought it would be quicker. My spools have an opening of 32mm internal diameter approx.
Though I have used wood, I have created a plastic version in case you want to print it too.
I have added a new support piece that will print into a stronger part, it only changes orientation.
