This is a remix of the PRUSA Extruder Idler MMU2S.
The improvement is that the pivot hole is increased from 3.4mm to 4mm to enable lining the hole with a 4mmx3.15mm aluminium pipe.
This decreases the pivot gap from 0.4 to 0.15mm improving the filament detector (FINDA) stability significantly. Alu pipes are available from model hobby stores.
Cut the tube to 20.5mm and chamfer one end for easy intertion.
