I built this part and found that friction between the inside of the spool and the crossbar was causing tension to build on the filament and erratic feed. I simply wrapped the crossbar in teflon plumber's tape and now I have a very smooth feed.

Thank you for your kind words.

Yours with the bearings should work better though.

Without yours, I never would have thought of the way that yours hooks onto the top of the printer. Now, if only I can get my printer extruding correctly so I can try building mine and try it out!
