Main credits go to Nozzle and DrAI for the original design of the t-slot nut and its remix for the Bosch GTS 10 XC.

I changed the design to mount an alloy dial gauge holder from one of the big chinese online shops. The original nut did not fit the t-slot of the GTS 10 XC so I remixed DrAIs design to use the original screws of the holder to mount it. No nuts required here. Had to increse the height of the middle part a little bit as the dial gauge holder has groove for its original sliding block.

I also created a design to mount a different dial gauge to the holder.
