Creality Extruder Idler Tensioner Arm, Ender 3 Bigger Holes
thingiverse
I modified the tensioner arm a little bit. Now it have bigger holes to fit the filament bush and the threaded bush for he tensioner roller. To remove the filament bush and the threaded bush from the broken part I have used a screwdriver and a plier. Now use an plastic or wooden mallet to took the filament bush and the threaded bush in to place. Be careful the holes would be narrow.
