I did a remix for this mount because I wanted it to be more precise during the axis movement and the the needle to be automatically pushed down.
I added some height to the model, and used just normal pen spring to push it down. There is a hole in the top of the mount for the 4mm spring.
The gauge that is working with this mount you can find very cheap here:
