Creality K1 SE side spool mount

This is a bracket and tubing holder for mounting the filament spool on the side of the Creality K1 SE printer. I just bought the printer a week ago, but I knew that I'd need a different way to mount the filament. The back of the printer is not easily accessible in my set up.

I decided to just clamp the bracket onto the side-bar/strut that I think is meant to stiffen the frame. I used M5 screws and threaded inserts for the bracket. The front of the bracket mates to the spool “spindle” that comes with the printer. 

I extended the tubing that leads to the filament runout sensor so I don't have to reach around to the back to push the filament into the sensor. The tubing extension will just slip into the tubing holder. It just mounts via an M3 screw on an unused, threaded hole that is in the frame. 

I took measurements for the locking interface for the spindle from another model. (I took nothing else from that model.) It was just an stl file, and it was for the K1 printer: https://www.printables.com/model/506827-creality-k1-side-load-spool-holder/files

I'm including the step files for the parts so the community can modify if they want. The files include the spindle mounting interface that seems to be common across many Creality printers. It's “spool_spindle_mount.step.”

I've made a few prints using this mount and it seems to work fine. Hopefully, it helps others, too.

I printed with the K1 SE with the 0.4 mm nozzle. I used Greengate clear PETG, and I just used the generic PETG that's in Creality Print. I did turn on supports for the “front-bracket-spool-holder_2.stl”. I printed it with the spindle mounting interface pointing “up”. The supported parts of the print were the spindle mounting tabs, and the channel that accommodates the central raised area of the sidebar.
