I don't like reverse bowden setup, I'd like my filament to go directly to the extruder. Bowden tube is however still used as a support for printhead cable.
Steps:
Disconnect bowden tube from the printhead
Use doublesided tape to attach bowden holder to the printbed
Push end of the bowden into the holder
Detach short bowden piece from the rear PTFE anchor and insert it to the extruder
