This part is an extended version of the Idler Holder holder for aluminum GT2 16 teeth idler.
It can hold an additional 2x625ZZ bearings that you keep in place using either a M5x20 or a M5 threaded rod that you cut at about 20mm long with 2xM5 nuts.
The bearings are really interesting in order to keep the belt parallel as much as possible.
On Scalar XL the X carriage is made so that the belt will be trapezoidal instead of parallel to itself. This can impact the precision of the machine.
It has no meaning to use this part however for the X axis.
This part is greatly improving this aspect keeping the belt parallel to itself.
Print this part 100% infill.
