I hated the run out sensor not being antiquate to tell if the printing filament isn't flowing. So I purchased the Automatic Filament Cutter. To be not surprised it doesn't just hook up to the run out sensor. I combined the runout sensor cover and Automatic Filament Cutter Adapter to create this gem! I printed with PLA with no supports and have it running into my filament dryer to keep my CF Filaments dry. The only sucky thing is I have to disconect the Automatic Filament Cutter to feed the filament into the printer. Other than that its a simple print. Modify it if you wish, I just want to give back to the community and all the great prints we have here!
