Dẫn Hướng Ống PTFE Cho MMU3

Because the filament is fed into the MMU unit at quite an angle in my buffer arrangement, I sometimes had the problem that the filament was pulled in by the pulley in such a way that the Idler output PTFE tube was not met (indicated by the red line vs. green line in the following illustration). 

The additional guide lengthens the infeed section and the filament is pulled in straighter. The part is designed so that it can be easily snapped onto the PTFE tubes. 

No supports needed if you use the model orientation shown in the picture below.
