BV3D Reverse Bowden Mount for Ender 3 Direct Drive

I have an Ender-3 V2 with a BIQU H2 direct-drive extruder. And I like mounting the spool holder on my printers, but this doesn't work super well with direct-drive extruders.

So, I wanted to install a reverse Bowden setup to put the filament input point back in a fixed position on the X axis arm. But some of the other mounts I saw to secure the input side of the Bowden tube seemed overly complex, or were threaded to accept a coupler.

I decided I wanted something small and quick to print, that didn't need a coupler. A light friction fit to hold the Bowden tube is all that's required. This mount fits where the original extruder and stepper motor used to be, on the left side of the X axis arm.

You can use M3 screws and nuts to secure it, but if you don't have any handy, I'm sure a couple of zip ties through the screw holes would work just fine.

I have a video about this, if you'd like to watch.
