This kit can help you improve your print quality by getting rid of filament slippage. Aluminum doesn't soften at printing temp like the plastic printed parts can, leading to less idler spring tension, filament slipping, bad prints.

Hardware is included in the kit, but you might also need additional screws to mount heatsink with fan, for an example.

  • 1 x Aluminum tension lever.
  • 1 x Idler bearing for 1.75mm filament.
