XL Filament Sensor Blocks (3x and 6x) with PC4-M10 Passthrough Fittings

This is a modified version of the official XL Filament Sensor blocks that were reworked to accept a PC4-M10 fitting. I have also provided a 2x filament sensor block.

I made this mod because I was tired of the PTFE tubes popping out the back of the official sensor blocks.

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.

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

I reshaped the fitting holes to allow for PC4-M10 fittings. I also combined 2 filament sensors into one block.
