This is a modified version of the official XL Filament Sensor blocks that were reworked to accept a PC4-M10 fitting held in place by magnets.
I made this mod because I was tired of the PTFE tubes popping out the back of the official sensor blocks. I also wanted to connect my PTFE tubes directly to my drybox and still be able to remove filament when the spool ran out.
I used these PC4-M10 fittings off Amazon, chosen because of their thread depth, beveled edges, and collet thickness. You can fit the whole fitting inside a 10mm socket.

I used this 10mm socket to install the fittings. It has just the right amount of thickness to allow it to tighten an inner fitting.

This design used 5mm x 5mm cylindrical magnets. The magnets are press-fit. The design has small holes on the back to allow magnets to be removed.

I finished off the design with some collet clips to make sure the PTFE tubes would stay in place.
