No, I have no idea 
I see your cut-out is perfect, did you measure the screen yourself, or did you find a datasheet for it (I have looked all the usual places for one)
I have a CNC-router myself, so I think I have to do something similar to what you have done.
Also, I read somewhere that the LCD-module is just stuck to the glass with a tiny amount of double sided tape and have come apart for some users, so be careful if you are holding everything in place using the two yellow bars, just a heads up
and finally, you don`t need to connect the 2 i2c-wires from the screen to the PI, there is a seperate i2c-bus connected through the flat-flex between the boards already this frees up the i2c-pins for IMU/other sensors
EDIT: the "somewhere" was a review on sparkfun product page;
"I purchased 5 touchscreen. Two before and three in January. Touch and display quality is superb. After two-three month of use (no rough use; handled with care), display LCD and front touchpanel (black bezel) break apart. They both are connected using a thin double sided tape. I was planning to use in industrial environment but after such issue, I dropped my plan to use it in industrial environment."
