Cr-10 Filament Topload Conversion

This is a modification to move the spool holder to the top of the frame.

I converted my CR-10S with a direct drive extruder, and I deleted the bowden tube. I mounted my spool to the top of the frame using standard t-slot hardware, but my direct drive bracket became too tall at the top of the print area and either hit the spool or pulled the filament at a bad angle. I decided to create a canted mount for the spool, and a filament sensor mount to match.

Mount the spool holder to the frame using 2ea M5x20 screws and 2ea M5 t-slot nuts. Mount the filament sensor adapter to the frame with 2ea M4x12 screws and 2ea M4 t-slot nuts. The filament sensor adapter accepts the standard CR-10S filament sensor switch and lid. A bowden tube guide is optional, but can be fashioned using PC4-M10 fitting and standard bowden tube. The X-axis bracket is to provide a method of securing the extruder wiring at the front of the frame instead of mounting at the standard location behind the frame.
