gauge bracket for MPCNC with Makita tool holder

While i build up my MPCNC i relized my tubes for the feet are not equal for some reason. in order to level the machine before the first cut i designed this brakcet to hold a gauge (Messuhr). This will help me to level the machine in all directions.

I think it will be helpfull fuor upcoming projects as well to measure the alignment of the good when i clamp it down as i plan to use a vise as well for my goods.

The diameter of the gauge is 8mm at the fixing

The bracket is designed to fit
