NyxCode did the bulk of the work (and shared CAD files!), but I needed a bit different. I chose to use uxcell M12 Cable Gland that better fit my SB2240 canbus cable, while also doing a quick mod to allow the use of a PC4-M10 connector to pass through the PTFE tube for filament.
The hole for the filament is just a sized hole for that purpose, no threads.
The gland hole fits that perfectly, and also shares space with a thermistor and a spring steel stiffener. I did turn around the gland so it's into the print space for better support, as the original design had it out the back, where the repetitive stress should be orders of magnitude less in my mind.
As per original, shared the cad files so further tweaks/variations could be made easily.
The author remixed this model.
