Ender Filament Runout Adaptor

thingiverse

I created this adapter in both PLA and PETG on my Ender 5 Plus printer, using clear dry boxes for my active filaments that can be quickly switched between my two machines when needed. This adapter securely attaches a 6mm white PTFE tube to the original run-out detector with a tapered connection, keeping the tube and filament aligned with the detector for smooth operation. I printed the adapter at a 45-degree angle to eliminate supports inside the cavity that slips over the bottom of the run-out detector. A small support and skirt were used to prevent the part from being pushed over during printing (see picture). Note: The design is intended to be a snug fit, so if you prefer a looser fit, you can scale it larger in your slicer by a couple of percent. After reconsidering my approach, I decided to ditch the adapter and directly attach a snout to the filament adapter for the 6mm PTFE tube. The second STL file is for a new detector cover with a snout that can replace the original cover on the Ender Filament Run-out detector. Simply move the switch to the new cover body with a snout and install it in place of the original cover. Update 2/18/20 I added an updated 6MM detector cover with a smaller hole for the filament to enter and exit the detector, resolving issues where some filaments would deflect enough to give a false "runout" indication. I also included a 4MM detector body that accepts 4MM PTFE tubes instead of the original one (6MM), as requested. Update 7/11/20 I added an STL file for a Spacer to adapt to a Dual Gear Extruder for Ender printers, inserted between the metal detector mount and the filament detector cover.
