Reverse Bowden Mount for Anycubic Mega S

This is a reverse bowden mount for the Anycubic Mega S with a direct drive extruder. 

Its purpose is to easily get your filament from the side of the printer to the print head without too much friction, e.g. in an enclosure etc.

It is designed to use a PC4-M10 push fitting to hold the bowden tube in place. You simply screw it into the top of the mount, self-tapping its thread.

Use two M4x12 screws to fasten it to your printer where the bowden extruder initially was.

I use a clear tube with an outer diameter of 4mm and an inner diameter of 3mm to minimize the friction that the extruder has to overcome. 

You might want to fasten the bowden tube to your wire harness.

Printable without supports in the standard orientation of the STL. You might want to add a brim due to the small contact area with the bed.

I've printed it in PETG with 4 perimeters and 40% infill.

If you want to print it in another material, you might need to adjust the scaling due to material shrinkage. 100.5% for ABS should be fine, I have not tested it though.
