Didn't like the way the 5mm pulley shaft had no support and with the high speed of Sailfish printing made it vibrate and flex. I made these to keep proper tension on the blets and steady the shaft.


Printed in ABS with the fallowing settings Infill 50% , Layer Height .2 , Shells 3
You need to print 4, once done the mounting holes will need to be drilled out to 3mm or 1/8".
Bearings used were 5X11X4 you'll need 4 and they press fit into the pillowblock.
Mount these on either end of the 5mm shaft with 8 M3X16mm bolts and 8 M3 nuts.

I mounted mine 49.5mm in from each edge and 14mm down for the first hole 38.5mm for the second. I filed the holes a very small amount so it could self align so there was no tension up or down on the shaft.

Oh and why do you need 4 of them? Are you using them on both rods?

What did you fill the hole with to help self align?

Where did you source the bearings?

No just down at the local hobby store, they have a stock of bearings of various sizes in bulk. Think they were $.75 each.

Yes!!! somebody actually came up with a fix for this major flaw in the frame design. Less ringing in prints!!!!

Thanks, and yes this did indeed help with the ringging I was getting.
