Creality Ender 3 / CR-10 Filament Runout Switch Mount for Direct Drive Setups

thingiverse

This replaces the X-axis motor cover/limit switch box one that contains mounts for the Creality CR-10 filament runout switch v2 and a PTFE tube fitting -- perfect for direct-drive setups. (The X-axis limit switch installs into this as well.) The filament spool holder will need to be mounted on the lower frame for the printer, which is where I prefer it anyway. There are a number of things available to accomplish that, [this is my design used in the photos](https://www.thingiverse.com/thing:4177681). Included are two versions of the mount; one that utilizes M3 brass threaded inserts for the switch mounting screws, and one with holes sized to drive M3 screws directly into the part. Using inserts makes for a more robust part, but you can probably get away without them. ### Parts List (4) 3Mx4mm threaded inserts (4) 3Mx20mm screws (I prefer hex socket flat head cap screw) (2) Small zip ties for cable management (1) PC4-M10 PTFE tube fitting (1) Creality CR-10 filament runout switch v2 ### Notes I printed this PETG which is my preferred material for printer parts, but PLA+ works great too, and regular PLA would probably be fine as well. It's up to you to figure how to utilize the switch, I have it connected to my OctoPi setup.
