Summary

It allows you to have the spool mounted on the top of the i3 frame.

Instructions

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.

Don't you have issues with this making the z-y plane flex due to the weight of the roll?

misan - in reply to Ramb0t

It troubled me too. It does not look ok nor advisable to put weight on the top of the frame. But as far as I can tell I see no difference on my prints (most of them not very tall) with or without the spool holder on top.

I really recommend flipping this on it's side, since there's a significant amount of shear force from the weight of the spool. When printed with the default orientation of the STL, the layers are subjected to this force.

I think you are correct, I haven't tested the printed version myself, but it makes sense.
