This was a quick PrusaSlicer hack. I simply combined the trapezoidal slider from the Ender X-Axis Mount project to the Runout En-Coder-Cube "Case Back" file.
I used PETG and it was a little tight when sliding in, so I did some light sanding. It is still snug.
This is definitely not rocket science. I had a need for this as the way I previously mounted the sensor was interfering with taller prints.
NOTE – January 3, 2023
I have had this on for about a week. The bowden tube that connects to the hotend loops and twists too much when it moves to the left.
I will move my sensor back to the upper left corner of the frame and mount it with t-nuts.
