Filament guide that helps align filament with the hobbed bolt.

After having several prints fail by filament feed issues, I designed this part to help align the filament prior to the hobbed bolt.

Since installation - I've yet to have filament roll off alignment.


I printed this out of PLA.

  1. Remove tension screws at top of E-Idler from Print head and open print head exposing hobbed bolt.

  2. Mount printed part just behind E-Idler on the print head.

  3. When closing and re-tensioning print head - feed filament through slot.

  4. Print away!
