I
ordered the printed parts for a Prusa i3 sometime in 2012 and recently started putting it together. I have most of the y-axis setup, but the y-axis idler is too tight; The Arduino Washer which has a Z809 bearing inside of it fits inside the y-axis idler, but it doesn't turn very well, the sides of the Arduino Washer push out against the inside of the idler, causing alot of friction. I haven't seen alot of y-axis idlers that look like the one I have included with my printed parts, so I'm not even sure that I have the right part. I saw one somewhere that sort of looked like it on Thingiverse but it was for a double bearing y-axis idler, and I tired fitting two bearing in there but it isn't wide enough.
Is there anything that can be done to fix this? Do I need to sand down the sides of the idler somehow? What's the recommended method for that? I haven't tried putting the belt on it yet, I don't that would alivate the friction on the sides of the idler though.
Thank you,
