Y Idler Tensioner Remix

thingiverse

This is a remix of just the tensioner from https://www.thingiverse.com/thing:1298757 I changed the tensioner on this remix, I added a hex socket for a nut on one side and I changed the width and added some nubs in order to use two new bearings instead of the ones the came with my printer. They didn't fit very well, maybe other printers came with different bearings but it didn't work with the ones I had. The bearings I used were F623ZZ flange bearings (2 of them together). With this modification, it runs much smoother than with my original bearings. Edit - I also changed the diameter of the screw that holds the tensioner pulley. The original I think was an M5, this now uses an M3 screw. I believe the length I used in mine was 30mm... so M3x30mm with a countersunk head, and a nylon M3 locknut. It was an extra screw that came with my printer, worked nicely. The bearings I used: https://www.amazon.com/gp/product/B06XSZ6JT2/ As a side note these are the same bearings I used in my X tensioner also.
