If you print from dry box, you don't need that tall spool holder anymore. But you still want runout sensor and this new holder/adapter will allow you to use the sensor in the original placement while cutting off the tall tower above it.
You will reuse the original screw. Don't lose the freespin washer! The original screw will thread itself (as a self-tapper), if it doesn't, just enlarge or punch through the hole - I have used hex screwdriver/allen key.
I have printed with PETG and 15% infill.
