Description
Remixed idlers taken from Fysfys's original design.
This version allows the idler mounts to sit on both sides of the extrusion. I remixed as I found the original was starting to bend inwards making the belts rub, this avoids the issue by putting a mount on both sides of the extrusion.
You need to print 3 of the straight ones and 1 of the 90 degree one, this allows fitting on the Y axis without hitting the wheel.
These are adjusted to incorporate spacers removing the need for nuts and other inserts, they are intended to accept toothed bearings also as an upgrade to the original basic bearing but will accept either.
This will require a longer bolt than the original, 35mm with a locknut should do.
