V9 Extruder Idler and Driven holder mod

thingiverse

The v9 extruder exhibited significant flexing during extrusion/reversal; thus, I made modifications to its idler and driven parts for enhanced strength and stability. These changes ensure that no movement occurs when the drive applies force on the filament. Post Camiel's upload of new 0.4 STLs, the driven holder was also made identical to his design. Additionally, adding an extruder corner alongside the idler significantly strengthens the entire extruder. The aluminum base may require drilling for secure fixation, which can be easily accomplished by aligning and fixing the corner in place with the drive plate, then drilling through the hole in the corner into the base plate and finally bolting the corner to the base. This modification, observed on the Orca 0.4, appears to be a simple yet effective enhancement. As for assembly, insert the idler into the driven holder with about 0.5mm clearance and proceed as normal.
