Printrbot+ Filament Guide
by Brett, published
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.
Remove tension screws at top of E-Idler from Print head and open print head exposing hobbed bolt.
Mount printed part just behind E-Idler on the print head.
When closing and re-tensioning print head - feed filament through slot.
- Print away!
